#200 Found in my home (on the floor, under
the edge of the carpet, near my
bed), downtown Toronto. G.
~~~~~~~~~~~~~~~~~~
Appears to be the larva (caterpillar) of a small moth. One possibility is
that it is the larva of the webbing clothes moth (see
http://www.insectslimited.com/wcmcl.gif ). In this case, you should find
evidence of feeding – including some webbing – on woolen items (including
the carpet) in the vicinity of where you found it. If no damage associated
with additional specimens is found, your critter likely simply is an
accidental intruder of no real consequence.

#199. Hi: We live in mid-France, Creuse, and today picked up a
piece of wood in one of our sheds and underneath were these giant grubs. I
didn't want to kill them if they are not going to eat our old farmhouse
which is full of oakwood. Be pleased to have any comments. Thanks. Juliet Scanlan
~~~~~~~~~~~~~~~~~
These are larvae (grubs) of large scarab beetles (Coleoptera: Scarabaeidae).
The larvae of some species of this family, as well as those of some stag
beetles (Coleoptera: Lucanidae) feed on decaying wood (including that found
in cavities in living trees), but are no threat to sound wood.

#198 I
found this little guy just a short way from my home here in Northern
Newfoundland Canada.
I have lived here all my live and
this is the first one I have ever seen, what is it. Preston Johnson
~~~~~~~~~~~~~~~~~~~~~~~~~
This is the larva of a sphinx
moth (Lepidoptera: Sphingidae). These larvae sometimes are called
‘horntails’ because of the fearsome-looking but harmless spine-like
projection on their tail end. Ed

#197 This spider was on my covered deck in Southeastern
Michigan earlier today. I don't know whether it came from the ground below
or from the roof up above. I used the zoom on my digital camera in the
second photo. I just want to know if the spider is poisonous or not. Thanks
for your time and attention. Any help you can give will be GREATLY
appreciated. Barb Cox.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a jumping spider (family Salticidae). These spiders are active
hunters with excellent eyesight. They do not spin a capture web, but often
use a ‘lifeline’ when they jump. Like virtually all true spiders, they are
venomous, but only a very few species are large enough to be able to
penetrate human skin. None are known to be truly dangerous, but a couple of
United States species can deliver a painful bite if mishandled (they are not
aggressive, and will not bite unprovoked). See
http://www.fact-index.com/j/ju/jumping_spider.html
for more details on these fascinating creatures.

Can't say I have an idea what
this is... although it seems to have some similarities to the glassy wing
sharpshooter. I'm from Stockton, California and it was found in my back
yard. Any help is appreciated. Thank you. MARC
~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a bee, but I cannot be certain of
the family. It might be a Megachilid, commonly known as leafcutter bees.
Ed Saugstad, retired entomologist.
Sinks Grove, WV
It has probably been awhile since you posted your
question #196 but I believe that is a Ambush Bug is the name no it is not
a bee. D. A.
No offense to D.A., but that is definitely not an Ambush bug. Ed is
correct that it is a bee, and I agree that it is of Megachilidae.
Although making an ID from the picture is difficult, I have to say it
looks very much like a Megachile maritima. J.D. Roberts,
Entomologist
(New posting)
It occurred to me that this could very likely be a
sexually dimorphic male of the Xylocopa genus (Carpenter bee). After
further research, I think it could possibly be Xylocopa brasilianorum, X.
varipunctata (http://www.insectaculture.com/xvaripunctata.htm),
or X. frontalis (http://zoo.bio.ufpr.br/hymenoptera/maracuja_visitantes.htm).

#195
I live in Florida - These bugs are climbing my walls in my home - I think
its some sort of tick but I'm not for sure. We have been flushing them down
the toilet or popping them (which then blood squirts out) They are light in
color - maybe a light grayish, they are not black - It makes me nervous and
I'm unable to go to sleep tonight - I just found them tonight and I'm
washing my sheets as we speak! Can you please help me identify these very
tiny little creatures - I need to know what I need to do to get rid of them
and fast! Thanks, D.W.
~~~~~~~~~~~~~~~~~~~~~
Although i am not sure my best guess would be that you have a case of
bedbugs... they most often prefer to feed on human blood but im not sure how
to get rid of them you could probably find some information on this
website.. they often live in and under beds cleaning that area very good
would be a good start. Joshua.

#194 Hi:
I live in Woodstock Ontario rural area and these bugs have invaded my
property by the thousands. They started at the end of July and fly
around between 3 pm to 6 pm, they are attracted to beer, wine and vinegar.
There size varies from !/8 - 1/4 of an inch in length. Sitting outside
during these hours is imposable. If someone can tell what they are and
how to control them, I would be very grateful. Thanks Tom
~~~~~~~~~~~~~~~~~~~~~~
This appears to be a picnic beetle (Glischrochilus
quadrisignatus; Coleoptera: Nitidulidae) Other members of this
family collectively are known as sap beetles. They often are pests in
gardens where they feed on ripe fruits (such as strawberries) and some
vegetables (particularly sweet corn that has been damaged by earworms or
corn borers). They appear attracted to the chemicals given off by
ripening or fermenting fruit/vegetable matter. See
http://ohioline.osu.edu/hyg-fact/2000/2047.html
for a fact sheet that includes some control
recommendations. Please bear in mind that they are extremely common in
the general environment, and complete control likely is impossible.

#193 hello, from Brewster, NY, these bees always come
around when there is food....what are they?
~~~~~~~~~~~~~~~~~~~~~~
This is not a bee. It is a Yellowjacket wasp. They are a
real nuisance around food in the late summer.

#192 Here is a picture of an insect that
was brought to me for identification. From the mouth parts and antenna
I believe that it is a moth of some type, but the transparent wings are
throwing me off. The edges of all four wings are scaled. It was caught in
south Alabama following hurricane Ivan. Rad.
~~~~~~~~~~~~~~~~~~~~~~~~~~
This appears to be clear-winged moth
(Lepidoptera: Sesiidae). The adult moths often are brightly colored, and
sometimes mimic wasps in appearance and flight behavior. The larvae are
wood-borers, and some species are important pests on trees and shrubs.
Ed Saugstad, retired entomologist.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This moth is the Scarlet-Bodied Wasp Moth (Cosmosoma
myrodora), it belongs to the family Arctiidae subfamily Syntominae.

Entomology, University of Illinois
~~~~~~~~~~~~~~~~~~~~~~~
Corrigendum to Number 192 – My thanks to Dr.
Hauser for correcting my careless mistake. I had totally forgotten about
Synotomids, but the shape of the abdomen alone on this specimen should
have warned me off Sesiidae.

#191
We have about half a dozen wicked looking black spiders drown in our pool
per week. They are mostly black with a large body where the legs are
attached and a relatively small light brown abdomen (back bit). I know it
has 8 legs but the front arm things are very long and sturdy giving the
appearance of having 10 legs. They appear to have two eyes on raised bumps
close to the front (I know they have 8). Finally they have very sharp and
relatively long fangs 2mm or so. The spiders are about the size of a toonie
and look like pictures of the Sydney funnel web and trapdoor spider. I know
the Sydney funnel web is indigenous to Australia but it is a similar shape.
I can send a picture if it helps. I am not too concerned about them in the
pool, they are dead, it is the live ones I am concerned about since we have
a large yard and two young children. Ian.,
Tsawwassen, British Columbia.
~~~~~~~~~~~~~~~~~~~~~~~
This is a male spider (you can tell by the enlarged pedipalps that look
another pair of legs at the front). Because you could see two relatively
large eyes, I suspect that it most likely is a wolf spider (see http://www.accessexcellence.org/LC/SS/wolf_spider/small_lycosid_face.gif),
in which case it is unlikely to be of human health concern. In fact, with
the exception of the hobo spider (an introduced species now found in the
northwestern United States and adjacent areas of Canada), I am not aware of
any large spider in Canada that is of medical importance. Like the
Australian funnel web spiders, the male hobo spider is more dangerous than
the female. A large adult male hobo spider can have a leg span up to 2.5” –

Photo was taken 09/19/04 in Clinton, TN. Caterpillar is about 4" long and
about 3/4" diameter. It was found on a Datura stem. What are the white nubs
it is covered with? Thanks. Deborah
~~~~~~~~~~~~~~~~~~~~~~~
I believe what you are seeing are the eggs of a parasitic fly (order diptera)
that uses the caterpillar as a live host on which to lay its eggs. Upon
hatching the larvae will feed on the caterpillar eventually killing it.
Bob.
~~~~~~~~~~~~~~~~~~~~~~~
The caterpillar in question (a large sphingid, likely a tomato hornworm),
has been parasitized by a small braconid wasp (Apanteles sp.).
The white objects are the cocoons spun by the wasp larvae after they emerge
from the host’s body. The large number of cocoons is the result of a
phenomenon called polyembryony, in which a single egg develops into two or
more (sometimes hundreds) genetically identical individuals. Ed
Saugstad, retired entomologist.

Hello, Please help me identify
this horrible flying bug. It's nearly 1" in length and after I captured it
in our rec room, I noticed it covered with red spider mites. It's the 3rd
one we've found. Should we just move residence or is it harmless? Thank
you. Lynn D,
~~~~~~~~~~~~~~~~~~~~~~~~
This is a carrion beetle (Coleoptera:
Silphidae) in the genus
Nicrophorus.
Also known as Sexton beetles or burying beetles, these interesting
creatures perform a useful (by human standards) role in nature by
consuming carcasses of small dead birds and animals. They are becoming
increasingly scarce in the United States, and at least one species is
considered federally endangered (see
http://www.northern.edu/natsource/ENDANG1/Buryin1.htm for
details). As a child 50 years ago, I saw them quite frequently on our
farm, but now, to find one is a real treat. By the way, the mites you see
on the beetle apparently help keep the beetle’s food supply safe by
feeding on fly eggs and also clean bacteria from the beetle itself. They
‘hitch a ride’ (phoresy) on the beetle to ensure that they arrive at the
food site. Ed Saugstad,
retired entomologist. Sinks Grove, WV

Hello, This bug bit me on the back of the neck. Found in New Berlin,
Wisconsin on 09/16/04. Can you help me to identify it? Thanks,

~~~~~~~~~~~~~~~~~~~~~~~~~
Appears to be an assassin bug (Hemiptera Reduviidae).
Most species are predaceous on other arthropods, but, except for some Latin
American species that transmit Chagas' disease, mainly are harmless to
humans. See also number 182.

I found this spider while I was mowing my lawn. I live in Buchanan, MI. It
was on my stone wall of my house... It is about the size of a closed
matchbox (like you would pick up at a bar or a casino). Just curious as to
what it may be... I looked into it a bit, and it looks like a "house
spider"? Anyone know what it is, and if it's anything to worry about? It was
near where my 2 year old likes to play...Thanks. Tom |

#186.
We have found several of these in our
home. We live in central NC. They are 1/2 inch to 1 inch long. What are
they? Richard
~~~~~~~~~~~~~~~~~~~~~~~~
Definitely a beetle larva; most likely a
Carabid (ground beetle) or close relative. Carabids comprise a very
large family of beetles, most members of which are predaceous on other
small arthropods. Ed Saugstad, retired entomologist.
Sinks Grove, WV

#185 This insect has the shape of a fly, is about 2 cm long
and maybe 2.5 cm across. The design on its wings is striking and probably
makes it easily identifiable to someone trained to do so. I found it in
late afternoon, in a meadow near Kingston Ontario which is on the north
shore of the St. Lawrence River. It flew from flower to flower, apparently
feeding. Many thanks to Sandra C. and Martin Hauser for helping me with an
earlier identification. Steven Burke
~~~~~~~~~~~~~~~~~~~~~~
Number 185 – Appears to be a large bee fly (Diptera:
Bombyliidae). The adults often are found on or around flowers; the larvae are
parasitic on other insects, including caterpillars and the egg cases of
grasshoppers. See

Hi - We found this guy crawling around our design studio this morning. Our
studio is in a very wooded overgrown area in the hills of Los Angeles, close
to downtown. This guy is about 7/8" long. Hope you can help us. We have a
pool going to see who is right.
Thank you. Glenn

This is a nasty
house centipede... I've been having a problem with those critters on the
third floor of my house because I'm pregnant and cant use pesticides, but
I've been told they become less of a problem if you use a dehumidifier
because they hate dry places.
Barb
~~~~~~~~~~~~~~~~~~~~
This is a house centipede (Scutigera
coleoptrata), common throughout much of the United States and Canada. They
often are found indoors, especially in basements and bathrooms. They are
much faster movers than most centipedes, and are predators on many other
arthropods. See

This interesting looking spider has made
quite a large web outside of our home in the back of our house. It has
been there for about a week now. It's body is about the size of a dime
and the picture is obviously from its underside. We live in the Hudson
Valley in New York State. Do you have any idea what type of spider this
is? Thanks.
~~~~~~~~~~~~~~~~~~~~~~~~
This is an orb weaver
spider (Araneida: Araneidae).
These spiders usually are noticed in late summer/early autumn as the
females fatten up prior to depositing their egg masses. Many species
feature banded legs such as are seen in your photo.

Hello. We've found 2 of these bugs in our home so far. they resemble
cockroaches with an elongated snout. They fly. Do you have any idea what
they are? We have found them upstairs in our spare bedroom and our
computer room in the window sill. They are apx 3/4 inch long. These were
the best pictures that I could take.
Thank you very much. I
have looked on the 'net to get an idea as I live in the lower mainland of
BC. We have not found any in any food areas. We keep our kitchen
clean. They have been found during the daytime. Thank you very very
much. Heather Lee.

#182...Looks like a "Kissing Bug". Hope you kept it for I.D.
reference! These can be hazardous to your health. Better do your research
on this one. Randy.

#181 Hi there,
About 3 months ago these little brown bugs started showing up in our
bathroom and kitchen. We also had a baby 3 months ago and, of course, have
had lots of new stuff coming into the house: furniture, clothing, etc. I
suspect they came in on something, or maybe in the cardboard boxes things
were packed in.
One night we killed 20 of these things in the
bathroom. Usually we only find 5-6 per night. The bathroom is directly
above the kitchen and we think they are following the pipes, though when I
startle them at night they run under the door frame in the bathroom. We
have seen the odd one in other parts of the house but suspect our cats are
catching them and playing with them. They are very small. At first we
could barely see them. Now they are about a quarter of an inch at most.
They are medium brown with long attenae and move quickly and erratically.
They do not stay along the walls but move across the floor in zig zags and
circles. They only come out late at night and are initially 'frozen' by
light but then start moving very fast. They can be easily crushed with a
paper towel or piece of toilet paper.
I suspect they are German cockroaches, but
they do not behave anything like the big black cockroaches I have
encountered in apartments in the past. They have been ignoring the
cockroach bait stations we put out and have not shown any interest in
garbage cans or any food left out in the kitchen. My husband and I have
started covering everything and taking away the cats food and water at
night and putting the plugs in the sink drains to ensure that these bugs
don't have any obvious source of food or water. Things are not getting
worse, but we aren't getting rid of them, either.
Can anyone tell me what these are and how to
get rid of them? I found one in the baby's nursery (next to the bathroom)
the other night and that was the last straw for me! Thanks.
Angela
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You likely are correct in believing that
you have German cockroaches (Blattella germanica), although because of the
blurriness of the photo, there is a remote possibility that they might be
brown-banded cockroaches (Supella
longipalpa),
which also are small and fast-moving. See
http://pested.unl.edu/bbroa.jpg for links to images of both
species. Also see

#180 These flying insects are all over our yards and came out
all at once in the past 3 weeks.
What are they? are they harmful? Thanks for your
help. Paul
~~~~~~~~~~~~~~~~~~
Crane Fly. These Daddy long legs are not
much of a problem, except they will lay eggs in your lawn which will
develop into leatherjacket larva. In large numbers the leatherjacket
larva can kill large areas of the grass by eating the roots. Unfortunately
in many parts of Canada it is against the law to use pesticides to control
this pest. The larva develop into Crane flies in the late summer and
are quite noticeable because of their size. More information on this web
page:
http://www.hdra.org.uk/factsheets/pc13.htm
~~~~~~~~~~~~~~~~~~~~
A
follow-up to the answer already posted: Although the larvae of a few species of
crane flies (largely of European origin) can indeed damage roots of plants
including many grasses and some young conifers
(see
http://www.forestry.ubc.ca/fetch21/FRST308/lab3/tipula_paludosa/leather.html
), the larvae of most species are detritus feeders in
aquatic or semi-aquatic environments, and those of a few aquatic species are
predaceous on other arthropods. Because so many other insects can cause damage
patterns very similar to that attributed to leatherjackets, some caution should
be exercised in determining the culprit responsible. For more general
information on this family of insects, see

#179 I've lived in Miami, Florida in the US all my
life. After purchasing a new home recently, we've been finding these nasty
little bugs all over the place outside. They seem fond of our basil plant,
mango tree and are usually clinging to our walls outside. The bug is
approximately 1 cm long and flies. I've been baffled because I've never seen
them before and have not been able to find them on the net. Any clue?
And yes, I put it in a ziploc bag :) Thanks, Juan

A
snout beetle (Coleoptera: Curculionoidea; some species are called billbugs).
Snout beetles form a very large complex of beetles in several families, and
many species are of economic importance. I am no expert in this group, and
so, although it bears a resemblance to Artipus floridanus (see
http://www.doacs.state.fl.us/pi/enpp/ento/images/artipus.jpg
for an image), I suggest that you take some specimens
to the Miami/Dade County office of Florida’s Cooperative Extension Service
for assistance in identification and control measures if necessary. See

for contact information.

#178 Can
someone tell me what this beetle is? I live in Greely, Ontario, Canada, near
a sub watershed, so I suspect that the bug came from the open windows. They
tend to like lurking the in carpet, but it does not look like a carpet
beetle. It is about 1/4 inch long and does not seem to like to fly.

~~~~~~~~~~~~~~~~~~~~~~~
This is a larder
beetle (Dermestes lardarius; Coleoptera: Dermestidae). They are cosmopolitan in
distribution, and will feed on just about anything that contains protein. In the
days before home refrigerators were common, these beetles often infested dried
meats. Today, they can still be found in many homes, but usually are not a
serious pest. We still find the occasional specimen in our house.

#175 Hi. We found this one at the
swing set, in our backyard. We found a second one at the other end of the
same swing set. We did not notice any food in either (large) webs. The
bodies are approximately 1 1/2 cm, with legs 3-4 cm across. We are concerned
because we have curious young children and dogs. We live in rural Quebec, 40
minutes northwest of Quebec City. It is middle September, 2004. What is it
and more important, could it be poisonous? Thanks. Sincerely,
The Lauckner Family

An
orb-weaving spider (Araneae: Araneidae), a very large family of spiders.
Although some can get rather large, none are known to have a particularly
potent venom, and most have ‘jaws’ (chelicerae) that are quite small for the
animal’s size. However, as in most instances of stinging/biting arthropods,
some individuals may be hypersensitive and could suffer an allergic reaction
to a bite.
Ed Saugstad, retired entomologist, Sinks Grove, WV |
#174 Hi there, we have found seven of these rather large slugs in our
garden in Port Elgin, Ontario. The largest measured over six inches and
appears to resemble "tiger' slugs found in British Columbia. Have these
slugs migrated from B.C. and more importantly will they survive the winter
conditions found around Lake Huron ? Thanks Len.
~~~~~~~~~~~~~~~~~~~
I’m no expert on gastropods, but this specimen bears a
strong resemblance to Limax maximus, sometimes known as the giant garden
slug, leopard slug, or spotted garden slug. This is a species introduced
from Europe, and now widely distributed in North America.

This dead one was found, along with a few other live ones of similar size
on the basement floor of a home in Saskatoon, Saskatchewan,

The white spot on it's back is just light
reflection. Any ideas? Heath
~~~~~~~~~~~~~~~~
Appears to be a very dead and desiccated small centipede, possible an
immature house centipede, Scutigera coleoptrata. These are commonly found

Any ideas on identity? David Larson, Bradford, MA
~~~~~~~~~~~~~~~~~~~~~~
Appears to
be the larva of a wood-boring wasp (Hymenoptera: Siricidae). They may be
distinguished from caterpillars by the presence of prolegs on the first two
abdominal segments. Although widely distributed, these insects never seem to
get abundant enough to be serious pests. Ed Saugstad, retired entomologist,

#171 Hi: I found this dead thorax (fly) today
(Aug_25_04)in the backyard of our home in Acton, ON. It is very big, the
length is ~2.25''. I have never seen such a big "fly" before. It would be
good to know how this insect behaves, what it likes and dislikes, etc.
Thanks, Will

This is an annual cicada, also called Dog-day cicada. These insects suck on
trees (you can see their long proboscis on the underside), but they can not
sting humans. They are producing the constant buzzing sound you hear outside
your house in the evening and during the night.

#170 Hi: This beautiful beetle was flying around the
garden lamp at 10:00 PM. In the air it seemed to be bigger, but landed, it
was ~1 inch long. When it flied, it has created noise, which you would not

on the ivy, where it was photographed. I was just curious, what is this bug,
and whether it’s harmless to humans/animals. Thank you,

#168 we found this
spider in our basement. it was of significant size and we started searching
to see what it was. the only spider we can find that resembles it is a
brown recluse but it was much bigger than the average size reputed for the

it but do we need to have a pest control place come in and spray?? thanks
for your help. Ange, Kingston, Ontario

Difficult
to tell from the photo, but definitely a male (enlarged palps) spider. If it
was quite large, it most likely was a wolf spider – these often wander into
buildings in rural/suburban areas. In any case, it is not anything to be
concerned about from a human health standpoint.

#166 Hi, we live in Vancouver, Wa. (AD not BC) and we found this little
creature wondering up our driveway. It has a nice large pinchers on the
front and it appears to want to sting from the rear when it is trapped. My
neighbor was pinched through his shirt on the tedious struggle to
capture this 1 inch nightmare. Can you help us I.D. this guy so we can know
if my neighbor has long to live or not? We know that the bug bites, but can
it sting? Bob

Hello, I live in central Wisconsin. I saw a dead bird outside my patio door.
But then it started to move. It freaked me out for a bit until I saw about 3
or 4 of these bugs come out from under it. It's black with orange strips
down it;s back as you can see. Kevin.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a carrion beetle (family Silphidae) of the genus Necrophorus (also
spelled Nicrophorus). These beetles are very useful because they get rid of
dead animals, which they bury in the ground. They are "good parents" because
they feed and guard their offspring. Some of these beetles are even
endangered.

#164 Hi my name is Nick and I live in Thunder Bay Ontario and found
this guy hanging off an old clothesline door on the side of my house and I
am dying to know what kind he is and any cool facts about it. With the legs
spread out I would say it was at least the size of a twoonie($2 coin), any
help would be great. It has a weird white cross on its back and color are
reds blacks white orange yellow.

I just noticed a strange
fly on the hood
of my car while parked in the driveway, it was all black about the
size of a small dragonfly but with only one set of wings it looked a lot
like a large mosquito but all black it had a long black tail that was thin
and round in about 4 sections and when i approached it it seemed to go on
the defensive and put its tail in the air like a scorpion would do to sting,
there didn't seem to be a stinger on the tail but i didn't want to get to
close to it to find out i did get some digital pictures of it, i guess i am
wondering if this insect is dangerous to my kids i guess, and what type it
is. This
is not a bug i have ever seen before specially in Nova Scotia.
Thanks. Dale. Shearwater,
Nova Scotia

#160 I found these
all on the ground and on a dead limb underneath a golden rain tree in my
front yard in Alabama. Please tell me what they are and how to get rid of
them with nontoxic substances. Thanks.
~~~~~~~~~~~~~~~~
I call them love bugs because they are always
mating. I too have thousands of them eating the pods of the golden rain
tree. I think they are some kind of box elder beetle. Good luck trying to
get rid of them. Clean up the pods, get rid of the golden rain trees, if
you let two live, you'll have 2000. I live in Oklahoma and have been trying
for several years. |

158 Hello, First, thank you for such a wonderful web site. I
found the various pictures to be fascinating. I stumbled onto your site
while trying to figure out the identity of some little insects that have
seemingly appeared over the past few weeks and are now starting to get out
of control. I have seen a few hundred throughout my house in about 3 weeks.
I live on Long Island, NY State (just east of Manhattan) about 1-2
miles from the ocean.
It seems like there are 2 different types but I think the smaller ones are
just younger versions. They fly although they do seem to prefer crawling.
The smaller ones are more brownish (almost rust colored) than the larger
ones which are black. The smaller ones look like they have 2 sections to
them, a body and a head. But, if you move the paper or bag they are on, the
"head" part either rolls under the body or it somehow retracts into the
body.When the "head" part disappears, the remaining "body" part just looks
like a little brown oval nub. The black ones also have 2 sections but don't
seem to 'retract' their heads.
The smaller brownish ones are about an eighth inch long lengthwise. The
black ones are maybe a quarter inch. We have a 10 month old in the house and
although I am sure they are not dangerous or poisonous, I still don't want
them on her or in her food. What do they eat so perhaps I can put out bait
to draw them in to one central place? How can I get rid of them? Will
a regular "room-fogger" be enough to take care of them? Thanks,
Mike

Although I am not sure of
the name of this bug, I had the exact same problem in my house. These
insects tend to congregate and build “nests” in old grain-based
environments, for example: an open cream-of-wheat box, a box of cereal that
has fallen behind the refrigerator (as was my case), open containers of
flour, etc. I suggest cleaning out EVERY cabinet and looking into
every box of grain, cereal, etc. that you have in the house. As well as
pulling out your oven, fridge, and other appliances or furniture that may be
hiding old grain or grain-based food items. In my case, I found a
half-empty bag of cereal that had fallen behind the fridge, as well as an
open box of wheat cereal in a cupboard – both items contained HUNDREDS of
these little brown and black bugs, along with their eggs and extended
families! After throwing away the offending food sanctuaries, the
problem went away! Cheers, Mark

blurry, but could be a black carpet beetle (Attagenus

Hi. I am from the

This spider is similar to # 41, 48, 49, 50 on the

I appears to
be one of these: black-and-yellow argiope, golden orb weaver, writing
spider, and yellow argiope. This web site has a good description
of this species:

#155 Hi, I'm from Dieppe, New Brunswick, Canada. I found this
huge spider in my backyard. I never seen a spider like this and this big in
this area. Any idea what type it is and if it is dangerous. To size it, the
spacing between the planks on the picture is 1 1/2 inches.
Thanks Yvon Hache

Argiope
aurantia (Araneae:
Araneidae). This beautiful spider goes by many common names, including
black-and-yellow argiope, golden orb weaver, writing spider, and yellow
argiope. They usually are not noticed until late in the summer when they are
nearing the end of their growth. They pose no threat to humans, and are
among the few creatures that I have witnessed eating Japanese beetles. Ed

This bug is all over a
tree in my yard in Arkansas. Virgil
When I
first saw this photo I thought it was a possible Coreidae species
nymph. It isn't, however, it is a true bug (Heteroptera) in the family
Rhopalidae. These are nymphs of one the scentless plant bugs,
specifically Niesthrea louisianica. These are not serious
economic pests but can be a pest to ornamentals such as hibiscus. They
have actually been studied and used to help control the weed,
velvetleaf. This is a very interesting submission. Great photo. More

#152 I live in New York City and have seen these little flying bugs
(.5 cm) all over my apartment in great abundance. Light doesn't seem to
bother them, so I usually see them during the day. They generally stay clear
of me and are usually found on the walls. If you know what this insect is
and how to get rid of these critters it will be much appreciated. - Thanks,

#151 Found a small cluster of these critters on the
inside of a sunny window (in Orchard Park, NY). They looked like they were
trying to get outdoors. Thanks, for your help.
Jim
~~~~~~~~~~~~~~~~~~~~~~
The critters in question are
male ants. As you can see they cannot bite because of poor jaws or sting.
They were simply trying to get out to a mating flight where they mate with
winged queens. They should be no threat at all. :) Bob

I
live in the state of Delaware located on the east coast in U.S.A. I was out
side my house washing my truck when my wife noticed this strange looking
bug/insect on our driveway. After she pointed in out to me, I immediately
grabbed my camera and took several pictures of it. I have never seen a bug
like this in my life. It was approximately two inches long and close to 3/8th
of an inch wide. I then went back into the house to get a jar to try
and catch it, but when I came back; my wife said that it had flown away. Any
idea what it may have been? Edward.

Thank you very much. I was the one that sent in the picture #150. I never
thought that there would be an answer or let alone a name. Now I have
that urge to actually go out and look for more unusual insect or bugs.
Once again, thank you. Sincerely, Ed Stubbs |

Hi - Something very similar to #113. Found in a head of lettuce in
Duncan on Vancouver Island, this guy measures about 1 1/4" to 1 1/2" long,
makes a small squeaky/hiss sound, and his legs can really grab hold with
tiny hooks. I think he just let out a smell too. I haven't been able to
identify him as any kind of Stick beetle so far, or cleoptera, but I think
he is from this genus. Hope we can identify this guy. Maureen and
Rob
~~~~~~~~~~~~~~~~~~~
You are correct about this insect being very similar
to #113, the ten-lined June Beetle (Polyphylla decemlineata; Coleoptera:
Scarabaeidae). If it is not the same species, it is an extremely close
relative.

#148 I just found this creature down the road from
my house (Richmond BC). Is it a type of earwig?
Shula. Richmond, BC.
~~~~~~~~~~~~~~~~
Definitely NOT an earwig, but photo not clear
enough for a definitive identification if the lateral projections are
legs, it would be a small centipede, but if they are spines/setae, it most
likely is the larva of a beetle. Ed Saugstad, retired entomologist, Sinks

Hi, As I was walking from my car
to my house, I noticed this, for lack of a better term, "thing" on the
ground. It appeared to be dying, possibly from getting run over. I tried
researching the "thing" and in about an hour, got nowhere. I was extremely
surprised to see that this "thing" was measured at just over 2" long and
just about 1" wide. I live in southwestern Ohio, near Cincinnati. I am
fascinated by this "thing" and would like to know exactly what it is. I know
I'm not in Canada, but would greatly appreciate a response anyway.
Thanks, Paul

This is a larva of a moth in the family
Citheroniidae (Royal or Regal moths- see
http://www.stetson.edu/~pmay/bugs/saturniid%201.jpg ).
From the photo, it is difficult to tell whether it
died from being squished, or to have died during the process of molting the
last larval skin to become a pupa. Although fearsome in appearance, they are
completely harmless. Ed Saugstad, retired entomologist, Sinks Grove, WV

We've seen quite a few of these moths
in our Victoria, B.C. apartment over the past few days of August.
They're photophilic, I think, as they often flutter around lamps. They're
distinctly two-toned: half of the wing (the end closest to the head) is
light beige, while the other end of the wing is a darker brown.
This moth was photographed resting on our kitchen ceiling. It's
probably a commonplace critter, but I would appreciate
identification, as we're wondering if it's the kind of moth whose larva eats
fabric or food!
Thank you, Julia

Indian meal moth maybe. I had some in my kitchen once that apparently came
from some food source in a bag - My dog's food? Flour? I can't remember
what the source was if I knew. Cary
~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is
Julia replying to Cary's identification. You're right, it was indeed an
Indian meal moth - thank you! And we located the source of the
infestation: a bag of peanuts that had been left open in a cupboard.
Needless to say, those peanuts are history. We've done some additional
cleaning up; so now, aside from the occasional straggler, looks like the
moths are gone. We'll be more careful of our stored dried goods in
future. Thanks again for your assistance.

Hello! This is not a pest as far as I know. We live in Bridgewater,
Nova Scotia. One day this little guy flew in the door and at first
appearance looked like a bee. Wrong! Upon closer inspection we noticed a
very "pug" looking face, no stinger and two distinct tiny wings sticking up
out of it's back other than it's primary wings. I wanted to take a macro of
it while still alive, but before I knew it, it started laying tiny orange
rice shaped eggs. I didn't want to disturb it but then it died by the next
day after laying a huge pile of eggs. This is why I have it mounted on a
pin. We've never seen anything like this before. Hope you can tell us what
it is! Thanks, Carole

This is a Bot fly or Oestridae. They are parasites in mammals, but none of

is a pest in cattle (Cattle Grub). Despite their nasty life cycle, they look
very impressive.
