Xestoleptura
crassicornis
(09/04/2004) some kind of beetle?
Dear Bugman,
I found this bug crawling in the hallway of our home in San
Francisco, CA. Sorry about the blurry photos -- it was a fast
mover and I'm not good with the digital camera. It had wings,
but didn't use them much. I've never seen this bug inside
or outside, so it piqued my curiosity. Thanks!
Julie

Hi Julie,
We can't seem to find an exact identification for your Long
Horned Borer Beetle, Family Cerambycidae, in our old Dillon
and Dillon Beetle Book, but fear not as we have several beetle
experts who will probably be notifying us shortly.
Ed. Note: We just received this information.
(08/09/2005) identifications
Hello - I was recently shown your site, and it is excellent. My
specialization is longhorned beetles, and in cruising around
I notice a number of incomplete or uncertain IDs for this
family. I don't know if you are interested in receiving this
sort of input, but if you are, I offer the following additions
to your identifications.
This is Xestoleptura crassicornis, an uncommonly collected
species which typically breeds in older, dried pine logs,
and is found throughout most of the forested portions of the
north and central coast, and inland in southern CA.Keep up
the good work. You are a valuable resource.

Colorado Potato Beetle
(09/02/2004) NJ Bug?
Hi,
We just moved into a 1920s cape about 4 months ago. Today
I went to open the garage door and saw this bug there. I have
NEVER seen this here or in NY before and was mesmerized. It
just sat there. Looked like maybe it was gnawing on the wooden
garage. It just sat there. I was able to snap this picture
without it budging. But about an hour or so later I came back
to look for it and it's gone.
Is it dangerous???
Celia, NJ

Hi Celia,
Your garage is safe, but your potato plants, tomato plants
and pepper plants could get eaten by the Colorado Potato Beetle
which was originally found only in the Rocky Mountain States.
The nationwide commercial growing of agricultural crops is
responsible for this pest's spread far and wide. Both adults
and larvae devour leaves.
Three-Lined
Potato Beetle
Editor's Note:
(08/13/2004)
Our site just went down for the month, and though we have
130 letters outstanding, we decided to photograph this event
taking place on our Datura plant. We noticed that the leaves
were being eaten and found large numbers of beetle grub, chewing
hungrily. They had an unusual viscous liquid on their backs.
We also noticed a small green and black striped beetle on
the plant. Guessing they were different stages of the same
species, we researched the Three-Lined Potato Beetle, Lema
trilineata, also called the Old-Fashioned Potato Beetle. This
beetle obviously went out of fashion when the Colorado Potato
Beetle became such a pest. Our Audubon Society Guide states:
"Voracious larvae gather in clusters on potato leaves, nibbling
lacy holes and eventually consuming all but the midvein. Unlike
other larvae of other potato-feeders, they are blanketed in
a wet froth of their own secretions. Adults can be distinguished
from the Striped Cucumber Beetle by the constriction behind
the thorax."Datura is a member of the potato family, which
explains the beetles presence on this hallucinogenic plant.

(08/12/2004) New pics, one unknown bug
Hey Daniel,
have one photo of an unknown bug,

and then a couple specials for you to add to your archives. I
seem to be getting better at my photos. The unknown
bug was
found in a drift fence array in West Texas, and none of the
researchers could figure out what it was. Can you?!
Wendy A.
Hi Wendy,
Your unknown beetle grub could be a larva of a Lycidae or
Lampyridae beetle, probably the former. . Your photos really
are great.
Stink
Beetle
(08/10/2004) Three Bugs from near Sedona, AZ
I was trying to find out what type of beetle we came across
on our last trip to the Oak Creek area of Sedona in June of
2003, when I found your way cool site. This photo was taken
near the part of Oak Creek where so many of the pretty
pictures of Cathedral Rock are taken. I think this might
be a type of ground beetle. It was about two inches long
-- when threatened, it put its head down while tipping
its rear end up. If you can identify any of these, I'd
be grateful.
Su -- Mesa, AZ

Hi Su,
Let's start with the Beetle. This is a member of the Family
of Darkling Beetles, Tenebrionidae, genus Eleodes which are
known as Stink Beetles. According to Hogue they are "smooth
shiny black beetles. ... They are medium to large (1 to 1
1/4 in.) and their wing covers are fused along the midline
making it impossible for them to fly. These conspicuous beetles
are usually encountered as they amble along the ground. Individuals
may also be found under stones and loose tree bark, where
the long cylindrical larvae also live. ... When a Stink Beetle
is disturbed or its wandering is interrupted, it stand on
its head and points it rear end into the air. For thi headstanding
habit, these insects are sometimes called 'Acrobat Beetles.'
Adults may emit a disagreeable though weak odor when handled."
Mottled
Tortoise Beetle
(08/08/2004) Hello
I was wondering if you could tell me what the attached bug
is. We are in our late 50's and have never seen this
bug before. It is on our morning glory vines in
Oklahoma. The gold spots are very bright.
Thanks for any information.
Gary

Hi Gary,
You have a photo of a Mottled Tortoise Beetle, Deloyala guttata.
The species is often found on the foilage of Morning Glories.
They are also called Gold Beetles by some people.
Cotalpa
species
(08/08/2004) Large yellow beetle
Bug Man,
My four year old son found this bug while camping… he
quickly became attached to it and played with it for most
of the morning! (a budding entomologist??); unfortunately
the close up photo did not come out very clear. It was
approx 1 inch long, bright yellow and unlike anything I’ve
seen around here (central Saskatchewan , Canada ). The bottom
was furry, much like the “Watermelon Bug” on your
beetle page – though not striped. It had large
legs that it used to help right itself when flipped on its
back. Quite entertaining for the crowd of kids it attracted.
A lady on the beach thought it was a “Japanese Dung
Beetle” which she claimed to have encountered while
farming cotton in the southern US – I’ve looked
up pictures and this does not seem to be the case. Assistance
with identification appreciated.
Thanks!
Guy

Hi Guy,
Identification is difficult because of the blurriness of the
image. We sharpened it as much as possible, and believe it
is a member of the genus Cotalpa. Here is a link
with some good beetle photos, including Cotalpa lanigera and
Cotalpa consobrina.
Puerto
Rican Long Horned Beetle: two foreign mystery bugs
(08/05/2004)
What an excellent and fun website! I thought you might be
able to help me with two mystery bugs that have proven baffling.
The second is this strange bug my entomology class in Puerto
Rico. We were stuck, and I still am – I can't place
it to order even, although the mouthparts and thorax might
suggest some weird orthopteran. This specimen was about 2
and a half cm from antennae-tip to the base of wings.
Thanks!
Robbie

Hi Robbie,
Thanks for the photos of the exotica. They are a mystery to
us as well. Your Puerto Rican Orthopteran looks according
to Eric
Eaton, to be probably a longhorned beetle (Cerambycidae).
Ed. Note: We just received the following
correction.

Green
June Beetle Infestation
(08/07/2004) big beetle bug
Hey.
We live near Raleigh, NC and are having a horrible time getting
rid of some bugs that have attacked our newly planted (last
fall) River Birch Tree. They have attacked only one
of the 3 trunks of the tree which is now pretty much black
and looks like it has been burned up. As you can see
in the close up photo of the bottom of the tree, there are
2 types of bugs – one we know is a typical “June
Bug”. The larger one favors the June Bug, but
is twice the size. We have tried normal ways of trying
to rid ourselves of them – which has worked on the June
Bug, but not the larger one. We have used Sevin Spray
and the Bag – A Bug. The Bag – A –
Bug doesn’t even draw them and the spray only kills
the one’s that are on the tree at the time. The
next day, more are present – many more!!! They
come by the 100’s. They are now moving onto my
tomato plants – so it is time to get serious!!!
Any idea what we are dealing with???
Going nuts!
Jim & Judy in NC

Hi Jim and Judy,
In addition to the smaller June Beetles, Phyllophaga species,
you also have Green June Beetles, Cotinus nitida. These beetles
are often called Figeaters, since they love to eat fruit.
Adults fly in large numbers, making a loud buzzing which is
somewhat similar to the buzzing of bumblebees. The beetle
feeds on many plants, eating roots, stems and leaves. Larvae
are common in rich soil and manure. We suspect that when you
planted the tree, you amended the soil with organic material
which served as a perfect habitat for the larvae. I would
strongly suggest you check with a local nursery for a control
method.
Flea
Beetle
(08/05/2004)
The other is a beetle, I think it's either a flea beetle or
a case-bearing leaf beetle. It's hind femora are enlarged,
but it also has yellow patches on the elytra where most flea
beetles have solid colored elytra.
Thanks again,
Dave
Hi Dave,
We agree that your beetle is a Flea Beetle, more specifically
Phyllotreta bipustulata. They vary from 1.6 to 2.5 mm in length
and are blackish with orange elytral spots. "The hind tibia
of Phyllotreta" according to Lutz, "are not grooved on the
outer edge, but slightly excavated near the tip and with a
spur at the middle beneath." A close relative that is similarly
colored but with different markings is Phyllotreta vittata,
which is common on cabbage.

Beetle Larva
(08/04/2004) bug in bend oregon
Dear bugman
i found your site today after i found this weird bug in my
BED. It looks to me like some kind of larva, maybe even a
termite? I don't usually freak out about bugs but i do not
like bugs in my bed i was hoping you could help me out it
looks to me like it has the head of an ant but flatter. it
has pinchers or a mouth or what ever that i can see it also
has six legs and the rest of it silghtly resembles a worm
or caterpilar i killed it olny because in was in my bed. i
had just woken up and didn't like the fact that it was sleeping
with me all night. now i have a dog but she has been with
my boyfriend for a couple of days and this thing moved fairly
fast so i don't know how it got in there. I deffinatly don't
want any more so if it is a larva i want the rest gone too.
I Live in Bend Oregon don't know if that helps. oh yeah i
have had it in a sealed container and maybe its the plastic
but it sort of stinks.

It looks to us like a beetle larva of some type. Larvae
with forms like that are predatory, which means it was hunting
prey and somehow found its way into your bed. Do not worry
about an infestation. We are forwarding the photo to a beetle
expert to see if he can narrow down the possibilities.
Monochamus
Borer Beetle probably M. scutellatus
(08/03/2004) Large black insect in northern Quebec
Recently while on vacation in Quebec (Saguenay Fjord area),
I saw this rather large insect on some wildflowers on the
side of the road. Taking its long antennae into account, it
was at least 3 inches or more in length. Any idea what it
could be?
Josh

Hi Josh,
You have sent in a photo of one of the Long Horned Borer Beetles
from the genus Monochamus. The larvae make a buzzing sound
when they feed, hence they are called Sawyer Beetles. Most
species of this genus attack felled or dead pines. We are
checking with an expert to get an exact species name. Our
beetle expert Dan wrote back: "if this dude is indeed black
as it looks in the pic, then it is probably Monochamus scutellatus.
dan"
Ergates
Sawyer
(07/22/2004)
Is Dan around? I have a new bug. This thing is about 1.25
to 1.5 inches long, not including antennae. Actual size, on
my computer. I bought another little digital camera. It takes
crappy up-close photos, apparently. :(
chris

Hi Chris,
You have one of the Borer Beetles, Family Cerambycidae. My
best guess is a Western Pine Sawyer, Ergates spiculatus. Males
have longer antennae. The dark head and prothorax and the
lighter elytra or wing covers are a good indication of the
species. Your specimen is small. Large males will reach 2
1/4 inches. They are attracted to lights. The eggs are laid
in dead pine and the larvae which take two or three years
to mature, are generally found in trees dead more than a year.
Adults sometimes visit flowers for pollen. Dan, one of our
beetle experts writes back: "daniel yup looks like ergates
to me i wouldn't refer to this as a pine sawyer though. Pine
Sawyers are in the genus monochamus (much smaller) dan"
There you go. I looked up ergates spiculatus after receiving
your email and the pictures that come up look pretty much
like the beetle I had. They sound relatively harmless. It
might have been a "small" one, but it was big enough. It surprised
me pretty good...almost as much as the first Jerusalem Cricket
I found.
Diabolical
Ironclad Beetle
(07/22/2004)
While walking briskly throught the canyon today, we noticed
this Ironclad Beetle, Phloedes diabolicus, ambling across
our path. Our first inclination was to move it out of harm's
way so an oblivious hiker or a malicious entomophobe wouldn't
step on it and crush it, despite its name which alludes to
the extremely hard body. On second thought, we turned around,
scooped up the beetle and returned home to our digital camera
to take some photos. After the photo session, we returned
the beetle to the canyon. Adult Phloedes diabolicus beetles
grow to about an inch in length. They are found under the
bark of dead trees, especially oaks, and are thought to feed
on fungus ridden wood. A similar species, Phloedes pustolosus
is a dull grayish black with the bases and apices of the elytra
whitish. Phloedes diabolicus is entirely black.
Gorgojo
a Mexican Weevil
(07/17/2004)
thanks for helping me to identify the other residents of my
home. fotograf this arthropods has become a hobby to me (there
is always somthing new) . theone named "bico4" here
is called "gorgojo" and this was about an inch long.
Daniel Vazques Abarca

Hi Daniel,
The "gorgojo" is a type of Weevil. These are beetles from
the family Curculionidae. They are frequently plant pests.
I am also going to forward your letter to our beetle expert
Dan, who may have additional information for you. We did a
google search for Gorgojo and found numerous sites in Spanish.
The weevil was identified as Insectos plagas: GORGOJO - Otiorrynchus
sulcatus. This site
states: "Los adultos, que aparecen a finales de primavera,
comen en los bordes de las hojas pero no tiene importancia
en cuanto a daños; las larvas son las realmente peligrosas
como plagas. Adulto alimentándos de noche • Plantas atacadas:
Muchos arbustos (Rododendro, Azalea, Hortensia, Evónimo, Camelia,
Glicinia,...), plantas perennes, anuales, bulbosas y plantas
de interior (Fucsia, Begonia, Ciclamen, Impatiens, Primulas,
Sedum,...). También Viñas, Fresas, Tejo y otras muchas plantas
de jardín y bonsáis que pueden morir en un corto intervalo
de tiempo. "
Grapevine Beetles (07/08/2004) Need help identifying
these beetles
Dear Bugman,
I have been searching the internet to see if I could identify
these beetles. I found them in my fuchsia hanging basket
on the front porch. So far this week I have caught 6
of them (always in pairs). Should I try to get rid of
them or leave them alone? We live in Northwestern Ohio
. Thank you,
Azah
p/s:Love your website and have included it in my fav

Dear Azah, Once again we turned to Dan who quickly replied
that these are Grapevine Beetles, Pelidnota punctata. "The
adults occur particularly on grape, both wild and cultivated;
the larvae live on decaying roots and stumps of various trees"
according to Dillon and Dillon.
Stag
Beetle
(07/08/2004) toe-biter or stag beetle... I'm guessing
This stag beetle or toe biter (or whatever it is) was found
in our dog's water dish on our back porch.
I "scooped" it out with the glass jar that you see.
(I didn't want it to die, but I also didn't want to let it
go until I could find out what it is.) The photos of
the beetles were taken today (July 8, 2004) near Chattanooga,
Tennessee. (I sent two photos hoping that my hand holding
the jar would provide some perspective. I thought the photo
without my hand perhaps had a better angle.) Hope these
photos are helpful to someone seeking more information. Thanks
for your help... despite the barrage of inquiries you receive.
I'm glad to know there's a place that can help "name"
the many insect-type "critters" out there!
Sincerely,
Anita

Hi Anita,
Your beetle, which you undoubtedly saved from sure drowning,
is a Stag Beetle, probably a Pseudolucanus species.
Tortoise Beetle Larva
(07/08/2004) What's this bug?
Dear Bugman,
I found this bug on some tomato and eggplants that were growing
on my porch. I’m really wondering what they are.
We live in central Pennsylvania . Your website is great
and I’ve been telling people about it :~) Thank you very much
for sharing your knowledge,
Leslie Howard

Dear Leslie,
At first we thought this was a Slug Caterpillar, but the curious thing about your
image is the debris on the back. We enlisted Eric Eaton's assistance to identify a Tortoise Beetle Pupa, and then Nathan wrote back correcting this misidentification.
Update (04/17/2006) I believe, now that you were able to identify the tortoise beetle larvae photo I
sent you can also put the following entry to rest as well. I found it under the
first Caterpillar listing. It looks very similar to an already identified toroise
beetle larvae photo found on one of your beetle pages - it too was green like this
one.
Again, great site!
Regards,
Nathan Cook
Eyed
Elator
(07/07/2004) click beetle
Attached, photo of an "eyed" black and white beetle
on the bark of an Arizona Ash tree, spotted (as it were) in
Austin, TX on June 12, 2004. Perhaps an Eastern Eyed click
beetle, Alaus oculatus?
Thanks for the great site, and service.
Jim

The Eyed Elator is surely a handsome Click Beetle. The
scientific name is Alaus zuniatus (we aren't positive on the
spelling of the species name), found in the southwest. Thanks
so much for the photo Jim. Keep sending us beauties.
Orthosoma
brunneum????
(07/07/2004) Unknown Bug
Found this on my door and was curious if you could identify
it for me. We live in North Central WV, and never saw one
before. Thanks.
Chad Fletcher

Hi Chad,
One of our contributing entomologists, beetle expert Dan,
believes it to be Orthosoma brunneum, but it is impossible
to be certain with your photo. The species, according to Dillon
and Dillon "breeds in crossties, poles, and all structural
timbers in contact with the ground or in moist, exposed situations.
Adults are also attracted to lights." That would explain the
appearance on your door.
Blister
Beetle
(07/07/2004) and something else I dont know what it is...
AWESOME site!
The other I have no clue what it is. It was taken on the shore
of Lake Michigan at the Sleeping Bear Dunes National Lakeshore...there
were hundreds of these hanging around. Any idea?
Josh in Detroit

Hi Josh,
One of our beetle experts Dan, says this looks to be one of
the Meloid Blister Beetles. The genus is Epicauta, the species
indeterminate. The family includes the European Beetle that
is used to make the aphrodesiac Spanish Fly.
Dynastes
tityus female
(07/07/2004) Not a Rhinocerous Beetle?!
Hi there -- I'm in south central Texas, and had the privilege
of meeting this giant beetle! She looks like a June
Bug, but way too big. As you can see, she doesn't have
the horned head, just a little round one, so I'm stumped!
Any ideas?
Oh, and just for fun, here's a shot of a red wasp trying its
best to get this GIGANTIC dead spider into an eave of the
house. I watched this wasp for at least an hour, during
which time she dropped the spider at least twice and drug
it back up the wall about 15 feet, all the way from the ground!
Not a great shot, but I filmed a bit of this also, if you're
interested I can send the AVI file. I love bugs!
Thanks for your great website.
Debbie
 
Hi Debbie,
The females of the horned scarabs, are with the horns lacking,
as in your specimen of a Dynastes tityus, sometimes called
the Eastern Hercules Beetle, and sometimes called a Unicorn
Beetle. Nice use of scale.

Hi Alan,
A Stag Beetle, probably a male Pseudolucanus capreolus. He
is very pretty. Glad to see you are not afraid.
wow! thanks for the quick response. i usually don't get freak
by insects - i love them, but i was a little nervous with
this guy in my hand!

Have you kept this beautiful Stag Beetle as a pet for the
past six months, or are the photos from last year?
Ground
Beetle unidentified species
(07/05/2004) Please help me identify this bug.
I live in Salisbury, Maryland and found this bug in my house.
I assume it's a beetle, but am concerned it could be a roach.
Just wanted to ease my mind. Thanks for your help.
Deb

Hi Deb,
Many of the Ground Beetles, Carabidae, are black with red
legs. I can't identify your exact species, but I can tell
you that they are predaceous, and will kill other unwanted
pests around the home and garden.
Metallic Green Cerambycid Beetle, Plinthocoelium suaveeolens
(07/05/2004)
Well I got a picture this time spotted the bug on a Cheatam
Wood tree here in Italy, Tx , will send one file due to size.

(Ed. Note: Here is Richard's original letter)
My unknown bug was long 3-4" with a long thin iridescent green
body, and with what looked to be a pair of long curved horns, it
was on a tree and flew off when approached, it looked like
some kind of a devil mantis. Location central Texas
I wish you had a photo.
Hi Richard,
Your bug is still unknown to me. All I can say is WOW, a large
metallic green Cerambycidae Beetle. These are long horned
wood boring beetles. I have recent contact with a beetle expert
named Dan and will try to get you additional information soon.
Your photo blew me out of the water.
Ed. Note: This beetle has been unidentified
until Eric Eaton wrote in with an ID from a photo sent in
on 10 July 2005. We now know this is Plinthocoelium suaveeolens.
june beetle infestation
(07/03/2004)
Hello,
Here's a picture of one of our trees in central NM that is
covered with these beetles. I think they are June
bugs comparing them to a picture ;on your site. For
3 nights we have been swatting the bugs inside and just noticed
tonight that all our pine trees are completely covered with
these guys chewing the needles. Do you have any suggestions
on how to get rid of them? We had lots of birds
here but none now that the bugs are here. Much appreciate
your speedy reply.
Sally Beers

Hi Sally,
It is dificult to tell exactly, but your photo does seem to
indicate a June Beetle infestation.. As you must
realize, they are very fond of eating pine needles. Sorry,
we have no erradication advice. You could try trapping
them at night when they are attracted to lights.
Daniel,
Thanks for getting back so quick. If you are interested,
here's what we did:
At night while all the beetles were munching away we shook
the tree and gathered them in a tarp. When the
sun came up they dropped from the trees and began crawling
to our house. Sprayed a bit on the edges of the entry way
and swept a lot up. Guess they are eating by night
and sleeping in our walls by day. Today will go for bug zappers
to try and get some more. Thanks so much for your help.

Palo Verde Root Borer, Derobrachus
geminatus: Due for a new name.
(07/02/2004) Big and Beautiful.
Hiya bugman!
I found this beetle in my garage this evening. We
live in Mesa, Arizona. The pic of it with the ruler came out
fuzzy, but it's a little under 3 inches long. That's about
as close as we were willing to get as it has pretty large
mandibles. I scooched it along a little to see
how it moves, and I think it was asleep because it jolted
like I had startled it. It moves slowly and seems
feisty, but then it's easy to get grumpy in this 105 degree
heat when all you want is to take a little siesta. I've
been to about 10 different beetle websites and can't find
it. Can you help? I love your website!!
Sherri

We stand corrected.
Correction
I was just going through the identifications and noticed that
someone made an error on an identification: Sheri (Mesa, Arizona)
sent in an image of a large long-horn beetle. It
was identified as a California Prionus. It is not
a California Prionus, but a different long-horn beetle. It
is of the genus Derobrachus, and is probably the species geminatus.

Update: Palo Verde Root Borer
(08/18/2007)
Hello,
I just wanted to let you know that the beetle on your page
2, Some one gave the correct on the family name, but didn't
give a name on what they are called. I live in Tucson Az.
& to my knowledge are mainly known here in the SW
They are called "Palo Verde" beetles, because
the female will lay their eggs in soil surrounding
the Palo Verde trees, which will hatch & live underground
for 3 years, feeding on the roots of the trees. They
are usually seen in the summer & fly in the early evenings,
they are attracted to light, which is why we always find
them by our front porch where the light had been on! I couldn't
find anything on your page under that name, so I hope you
find this helpful. They are the biggest bug I'll ever want
to see with pinchers! I've enclosed a couple pictures.Thanks,
Wendy Warunkiewicz
California Prionus
(07/02/2004) Hello,
Thanks to your well-designed site, I was able to identify
the large beetle in my driveway as a Prionus californicus.
This was in Orange, California on July 2nd, 2004. Thought
I'd share my photo with you, in return for the quick and detailed
information.
Thanks again!
Marc McNaughton

Thank you for your kind words Marc, and also for the high
quality photo. The
species, according to Essig: "ranges along the Pacific Coast
from California to Alaska and is also reported from Arizona,
New Mexico, colorado, and Nevada. Adults are nocturnal and
fly in midsummer to fall. They are readily attracted to lights.
The adults make a loud humming noise on the wing and often
strike the windows at night with an impact that almost breaks
them."
Cottonwood
Borers
(07/02/2004)
This bug was found in Oklahoma.....can you tell me what it
is?
Thanks,
Judy Campbell

Hi Judy,
You have Cottonwood Borers, Plectrodera scalator. They are
beetles from the long-horned beetle family Cerambycidae. These
are very large black and white beetles. We have several photos
on our beetle page from last year. Adults are common around
cottonwood and poplar trees and the grubs bore into the wood
of those trees.
Carrion Beetles
(07/02/2004) I Have No Clue! but we do!
If you can see from the picture- I took some Coquina
Shells home from the beach- laid them out to dry
and..... I saw about a dozen of these black bugs coming out
of the shells the next day- and have no clue if
there were brought home from the ocean, or were from my back
yard. I'm without an identification book here,
and found your site-- can you help identify these awful looking
things?? All I can say is thank goodness they are outside!!

The real reason you should be happy the shells are outside
should be the stench. Obviously the shells stank badly enough
to attract flies as well as Carrion Beetles, Silpha americana.
These beetles are attracted to putrification in many forms,
including dead animals and fungus. They perform a necessary
scavanging activity as well as being valuable to forensic
science by helping to determine the time of death when bodies
are discovered.
P.S. Your photo is awesome.
Thanks for your quick reply!! Yes, I know the smell is unbelievable-
I knew that would happen, but the beetles!!!! No Way! I've
just never seen them before, and my first reaction was, well,
a typical "girl" response--- Unfortunately, I have noone
around with the stamina to dispose of these .... things.....-
I assume they will wander away on their own??? Thanks again,
just another typical, "you'll never guess what happened
to me" story!

White-spotted Sawyer
(07/01/2004)
Noticed here in southern New Hampshire (Merrimack) and I have
never seen anything like it.... Any ideas?

Totally awesome photograph of a White-spotted Sawyer,
Monochamus scutellatus. These large Long-horned Borer Beetles,
Family Cerambycidae, are black with a bronze sheen and white
markings. The males have extremely long antennae, like your
specimen. They attack felled or dead pine trees. Because the
larvae make a buzzing sound, they are called "Sawyers". Though
they usually feed on freshly cut logs, they may attack living
trees.
Firefly
larva
(07/01/2004) Hi,
Firstly let me congratulate you on a wonderful website. Within
minutes of arriving I was able to identify that one the two
strange bugs I found was a 'House Centipede'. The other I'm
having more problems with. I found the insect in the shower
on a recent holiday to Greece. I think it may be some sort
of beetle larva but would love to know which one. It reminds
me of the ladybird larva but was considerably bigger at 1.5
to 2 inches in length. Any help would be much appreciated.
Regards,
James Stratton.

Hi James,
It is definitely a beetle larva. It looks like one of the
Lampyridae or Firefly larvae. They are predatory.
June
Beetle
(06/30/2004) Hello,
Any idea what bug this is? I found it flying outside near
the top of my birch tree.
Thank you
Hal

Hi Hal,
You have a species of June Beetle. Your photo isn't the best
quality and it is difficult to tell if the color is really
golden or if it is a reflection from your flash.
Spotted
Cucumber Beetle?
(06/30/2004)
I've been watching an insect in my sun garden for two days
now. It looks a bit like a lady beetle or lady beetle larva,
but the head seems different - just small and black - no big
platey head with white patches - and it has very long antennae.
Also, it is yellow. It has eleven black spots - a row of three
near the head, the middle spot being in a "v" shape,
and then two rows of four. Can you please tell me what it
is? Sorry that I don't have a camera good enough at closeups
to photograph it for you (if you can recommend a good digital
camera for photographing insects and flowers, please let me
know - I am thinking of requesting that from hubby for Christmas...).
Thanks, and I love your site!!
Julia
Hi Julia,
It sounds like a Spotted Cucumber Beetle, Diabrotica undecimpunctata
howardi. Here is a photo I downloaded from this site
which has lots of information on this garden pest.
That's
it! That's it! Thanks! Julia
Stag
Beetle: Psuedolucanus capreolus
(06/29/2004) Bugman,
Any idea what type of beetle this is. I found it crawling
across my kitchen floor. It's a dark brown color with orange/tan
legs underneath the body. A nickle is a shown on
the attached photo for size comparison. I live
in Madison, Wisconsin (south central Wisconsin).
Where do they nest?
Are they poisonous?
Do they come in numbers?
Do I need and exterminator?
The Stag Beetle photos are beginning to arrive. You have
a species from the genus Pseudolucanus, probably P. capreolus,
a male that can be identified by his large jaws. The grubs
can be found in decaying logs and wood. The adults fly and
are attracted to lights, which explains the presence in the
kitchen. They do not swarm, but are seasonal, so you may encounter
additional specimens. They are not poisonous, and the jaws
can pinch, but will rarely break the skin. You do not need
an exterminator.
Stag Beetle: Lucanus elaphus
(o6/28/2004) not sure what this is..
Hello...
I don't know anything about bugs, but this huge thing greeted
me on my deck railing last week, near Richmond, VA.
It was close to 2 inches long and didn't move when I approached
to take the pictures. Unfortunately, the pictures are
a little fuzzy, as I was handholding the camera.
Any ideas? I've never seen anything like this before.
Guy

Hello Guy,
What an impressive Male Stag Beetle, Lucanus elaphus, you
have. We have gotten photos of Stag Beetles in the past, but
always from the genus Pseudolucanus. Your specimen has impressive
mandibles. These beetles occur in the South. They are usually
found around the stumps of oak trees, but they do fly and
are attracted to lights. Females which have smaller jaws,
are reported to be very rare.
Tortoise
Beetle
(06/28/2004) Gold Bug
Dear Bugman
Hope you can help ID this bug. Found amongst grass/meadow
flowers in China, Guangxi. Thought it was a small button at
first being about 10mm across, shiny, golden/bronze with
a domed transluscent 'plastic' disc for protection. Small
feelers scanned ahead and when disturbed the four suction
cupped feet clamped the body down. May have been able to fly.
Sorry for the poor image.
Bruce

Hi Bruce,
I cannot tell you an exact species name since I don't have
a guide to Chineese Beetles, but it is a Tortoise Beetle,
Family Cassidinae. They get their name from their form. Many
of them are beautifully colored in life, but the golden hues
rapidly fade after death. Many feed on sweet potatoes and
other Convulvulaceae, like morning glories.
Cottonwood
Leaf Beetle
(06/27/2004) Hello Bugman,
I have to tell you just how interesting I have found your
website. It has become quite habit forming. I am attaching
3 photos of a bug in various stages. These army of
creapers have taken over my Weeping Willow Tree and
are eating it up. Can you please tell me what
they are and the best way to get rid of them.
I live in NorthEast Arkansas.
Thanks so much for your time and knowledge.
Cathy Smith
 
Hi
Cathy,
Despite being called the Cottonwood Leaf Beetle, Chrysomela
scripta Fabricius, this pest can also be found on willow
trees, as you know. I would check with local agricultural
experts regarding control, now that you know what you have.
Both the adult on the left, and the larva on the right will
eat leaves from the host trees. We found some information
on this site.
Good
Morning,
Thanks so much for emailing me back so quickly. I
am very happy to know exactly what kind of bug this is that
is bugging me and my willow tree. I will get in
touch with the Agricultural department today. Thanks
so much for your time. I hope this email finds you having
a wonderful day. Best Regards,
Cathy Smith
Cottonwood
Borers
(06/26/2004)
Hi I found your site after looking through about 50 websites
trying to identify two bugs that I found in my backyard. I'm
from Amarillo, Texas if that helps. I have attached pictures
of these bugs. I have never in my life seen anything that
resembled these two bugs! They are about 3-4 inches long with
large antennae. They have pincher like mouths and are hard
bodied. They can also fly but I don't think they can go far
because they are so large and heavy. Please help me figure
this out because I have a young son and I'm afraid to send
him out in the backyard thinking he might get bit by one of
these. Thank you so very much for you help in my search!
Lisa

Dear Lisa,
You have Cottonwood Borers. They are beetles from the long-horned
beetle family Cerambycidae. These are very large black and
white beetles. We have several photos on our beetle page from
last year. Adults are common around cottonwood and poplar
trees and the grubs bore into the wood of those trees. They
will not harm your children, but a huge infestation may harm
your trees.
The Larger Flat-headed Pine Borer
(06/23/2004) Extremely Large Beetle!!!!
Hello,
Although your site was informative and quite fascinating
I was unable to identify a very large beetle. This beetle
was actually found on my sisters shirt right at the base
of her neck. I however spotted it before she could freak
out too much... it was really quite hilarious to see her
dancing around trying to reach it. I did of course pluck
it off her and rescue the poor thing. I live in British
Columbia, Canada and have not seen a bug like this before,
and doubt that I ever will again. It was very sleek in body
style and looked like it had a velvet shell and was soft
to the touch. It was none aggresive and quite content to
just sit on my arm. However if you touched it or prodded
it would scurry with surprising speed on its padded
feet. I believe it was about two inches long if not more...
and was neat to watch. I got about 10 photos of it so hopefully
you can help my curiosity by telling me what it is.
P.S. : I hope you like the photo, which I shall send in
the email follwing!
Tracy Sherwood

Dear Tracy,
I can't believe you didn't think I would love your photo
of a Larger Flat-headed Pine Borer, Chalcophora virginiensis
[*Correction: Chalcophora angulicollis].
It is a species common in pine areas. They are members of
the Metallic Wood-boring Beetle Family Buprestidae. The
larvae bore under bark or in wood, attacking either living
trees or newly cut or dying logs and branches. Adults run
and fly rapidly. I found a website
which states: "Individuals may be seen resting on sidewalks,
on walls, and may actually land on people, especially if
they walk around in bright clothing. This may be quite disconcerting
to those that are intimidated by large insects."
Thank
You ever so much for replying so quickly! And you are right
it is definetly a large pine borer. And I am also happy
you liked my pic! Just graduating from high school ( Grade
12) and am planning on following my dream of becoming a
professional photographer, I am tickled pink to hear that
you liked it! Once again thanks ever so much for helping
me out! And thanks for the awesome and informative website!
*CORRECTION
Re: help identifying beetles when i looked at the beetle
pix previously the only missID i saw was chalcophora virginiensis
since the bug was from BC it should be c.angulicollis. no
big deal u did a good job on the others but i would be
very careful putting species names on any beetle because
there r usually many closely related sp. in any given genus
feel free to send me some puzzlers if u get any thx

(06/10/2004) Prionus Beetle
This is an email forwarded to me by my aunt who found this
interesting species of wasp in her backyard...Any ideas???
Rachel
"Hey,
I know you will think I'm being weirder than usual, but I
happen to find all animals (even insects) very fascinating
even the freaky ones!!
I was outside this am playing and cleaning up my Danes, then
started cleaning the pool. I found this bug dead in one of
the baskets. Talk about freaky!!!!!!!!!! Has anyone ever seen
this or know what family of insects it is from? Its back-end
is striped like a yellow jacket, but its huge!! It measures
3.5 cm from the tip of its tail to its mouth, and it has 2
different sets of wings, the back wings are clear with dark
brown veins and are 2.5 cm long, and its front wings are dark
brown/red and are 2 cm long but are shaped differently than
its back. its long feelers/antennas are almost 3 cm long.
and it has HUGE jaws (I think they are called mandibles) but
science was a LONG time ago for me. It also appears to have
a stinger out its back-end! WOE
~~~~ Debbie"
 
Hi Rachel and Debbie,
You found a Prionus which is a member of the Long Horned Borer
Beetle family. These are among the largest beetles in California
as well as other parts of the U.S. The grubs bore into the
roots of Oaks, Madrone, Cottonwoods and some Fruit Trees.
They will also feed on Eucalyptus. Adults emerge in summer
and are often attracted to lights, which might explain its
drowned presence in the pool.
Ed. Note: We just recieved this information.
(08/09/2005) identificationsHello - I was recently shown your
site, and it is excellent. My specialization is longhorned
beetles, and in cruising around I notice a number of incomplete
or uncertain IDs for this family. I don't know if you are
interested in receiving this sort of input, but if you are,
I offer the following additions to your identifications.
The beetle pictured is Prionus (Neopolyarthron) imbricornis
(or much less likely, P. (N.) debilis; that level of detail
is lacking in the photo), but with that many antennal segments,
cannot be either of the two Californian Prionus (Prionus)
species. Cheers.

Eastern Hercules Beetle
On Wednesday, June 9, 2004, I found an eastern Hercules
beetle resting on the gas pump near my home in Statesville,
NC. I know that he is male because he has the most beautiful
set of horns. He was quite docile whenever I found him;
he may have been hungry or thirsty, I'm guessing. Anyway,
I am keeping him in a ventilated clear box about 10"
by 18" with a layer of a mixture of compost and mulch.
I put a forked stick in there for him to climb on and a tiny,
shallow bowl of water which I change every day. He burrows
under the compost from time to time. He seems to like
peeled apples and he has now become much more active.
I've noticed that he is eating a bit of a fresh apple slice
every day. He tries to rear up on his hind legs whenever
I stroke his back. Unbenowance to me, I didn't know
that he is more properly called a Hercules beetle, rather
than an eastern rhinoceros beetle. I had already
named him Hercules! From what I've read, the Japanese
rhinocerous beetles are sold as pets and can live to be three
years old or so. What is your opinion of my keeping
him as a pet? I enjoy watching him, but I certainly
don't want to shorten his lifespan by keeping him captive. If
it's okay to keep him, am I properly caring for him?
My grandchildren love "Nana's critters", as they
call the numerous dead bumblebees, dragonflies, and other
insects I've accumulated. This is the first time
I've tried to keep a live insect. Any advice you
can give me will be appreciated.
Diane Patrum
Dear Diane,
We have no experience keeping Hercules beetles alive, but
they can be raised easily in captivity. Captive raised specimens
are usually much larger than wild beetles. It sounds like
you are doing everything correctly, and I see no reason why
you shouldn't keep your beetle as a pet if he is bringing
you pleasure. You might want to try a google search with
the word captivity as well as Hercules Beetle to find additional
information. We would love to have you send in a photo if
you are able. Have a nice day.
Daniel
Cotalpa
consobrina
(06/09/2004)Golden Beetle
I just found a beetle that looks very similar to a June beetle
but is more pale golden in color and does not have long antennae.
It's topside looks somewhat like the Hercules or Unicorn beetle
without the spots. It also has somewhat of a tiny triangular
shape at the top intersection of its wings and its head somewhat
like the Eastern Hercules Beetle has. It is kind of shiny
as though the body is armored. I have drawn a picture of it
but the picture does not really do it justice as the green
you see on its wings and behind the head is more of a dotted
green hue instead of stark lines. In fact I just looked at
it again and the color behind the head where you see the two brown
blobs is morelike two B's, very lightly brownish
hued, facing each other The white dots you see represent
the shine on it. When flipped over, it is ribbed and looks
more the color of a brown colored honey or horehound and its
legs have somewhat fuzzy hairs on the outside edges while
the chest section is fuzzy (somewhat like a bee is fuzzy).
It also seems to be somewhat fuzzy under the lower portion
of the wings. The hind legs get lighter at the upper portion
of the leg. The undertail section is more closely ribbed than
the upper section. Centered between its second set of legs
and back legs is somewhat of a diamond shape with a line going
through the center of the diamond (Head Tail). Your
help in identifying this beetle would be tremendously appreciated!
Sincerely, Diana Isham, Grantsburg Wisconsin

Hi Diana.
We got another letter from New Hampshire reporting a similar
beetle. We have decided it is probably Cotalpa lanigera which
is approximately an inch long and entirely yellow with a metallic
luster. It occurs near catalpa trees. It could be your beetle.
Thank you my friend! I looked up Cotalpa lanigera and thought
momentarily that it might be it because it looks very much
like it but its wings also looked too white. I then did a
bit of research, found it on the following website
and was delighted to find a lovely photo of my beetle just
below Catalpa lanigera. It is called Cotalpa consobrina and
is a native Arizonan like myself! I am so amazed! I lived
in Arizona for the first 15 years of my life and never saw
one of these! And now I’m wondering if it’s a native only
in Arizona, and if so, how did it end up here in Wisconsin?

Hi Diana,
We haven't been able to locate any information on the extent
of the range of Cotalpa consobrina.
Ironclad
Beetle
(06/07/2004) Still ALIVE and Unidentified!
Dear Bugman,
My son and I was clearing up some brush on our property and
came across this bug. We have a cottonwood beetle we
collected 4years ago and figure it was along the same family
but we have been unable to correctly identify this one. It
has similar identifications. Would you have any knowledge
of this such bug? What it feeds on? etc. It doesn't
seem to be in any hurry since the second we spotted it sitting
on the same piece of wood.
Also, do you have any knowledge of how ot properly preserve
insects. After 2-3 days they all seem to end up smelling like
bad eggs. we have placed the cottonwood beetle in an airtight
cube for viewing (NEVER TO BE OPEN AGAIN). We have visitied
our library for reference but have had no luck. We have read
that a museum in London has a 30,000 collection.
Attached is also a picture of one of many walkingsticks roaming
around.
Thank you for your help,
Darin, Melissa and Spencer

Ed. Note: Before we even had
a chance to begin to research this unknown beauty, the family
from Bulverde, North of San Antonio, Texas emailed us a link
that identified the Ironclad Beetle, Zopherus nodulosus haldemani.
According to the site, little is known about the biology of
the species. The information continues "Larval and pupal stage
of this insect have been collected from the dead wood of pecan,
which apparently serves as the developmental site for this
species. Adult beetles have been collected from trunks of
oak trees in the College Station, Texas area. Adult beetles
are thought to feed on lichens growing on trunks of these
trees. This beetle can be found clinging onto the trunks of
trees or outer walls of homes in wooded areas." In the Los
Angeles area, we have a totally different beetle known as
the Ironclad Beetle which goes by the scientific name Phloeodes
pustulosus, but also belongs to the Family Zopheridae.
Hi
Daniel, Attached are a couple of better photos of the ironclad
beetle. We are in the San Antonio area and have a great selection
of insects. We have also found 3 species of walking sticks-we
have lots of cedar trees in which they hide. We have come
across some katydids, stag beetles, and many different butterflies
(although the Tiger Swallowtails are the most common). We
are looking for the best way to preserve them-when I was a
kid, I used pins, but I would prefer a longer term method
without the smell and worry of other parasites feasting. Also,
our humidity is higher here, which may be a concern. Thanks
again for all your help.....
Darin, Melissa, and Spencer
 
Hi
Darin, Melissa and Spencer,
Pins are still the standard method for collections, and of
course, dermestid beetle larvae are always a problem as they
can quickly devour a collection. An airtight case with moth
crystals that are frequently replaced is an option. There
is an excellent book, An Introduction to the Study of Insects
by Donald J. Borror and Dwight M. Delong that goes into very
specific detail about the preservation of each type of insect
in your collection. It is a worthwhile investment. Here
at www.whatsthatbug.com we prefer our insects alive and do
not have a collection. Thanks for the new photos. We will
post an additional one.

Hercules Beetle or Unicorn Beetle
It has stickery feet that tickled on your hand. He isn't afraid
of anything. I found him walking on the parking lot at Wal-Mart
down here in Lumberton, Texas. Sorry about the clarity of
one photograph he kept moving and I am just leaning how to
use this camera.
DeeDee Revia

Hi DeeDee,
Thank you for the photo of an Eastern Hercules Beetle, Dynastes
tityus, also known as a Unicorn Beetle. Unicorn is something
of a misnomer, since your side view reveals additional horns.
These are among the largest American Beetles.
Eyed
Elator
(06/06/2004) Beetle with EYES!
Hi Daniel, We have many different beetles on our land. The
one we saw today (photo attached) is by far the most interesting.
The body is around 3cm long. Do you have a good online source
recommendation to ID future beetles that we find? (Besides
your fab site, of course!)
Thanks, Sandra

Hi
Again Sandra,
We are still trying to get a positive species identification
on your green horsefly. Your beetle is an Eyed Elator, Alaus
oculatus. These are members of the Click Beetle family Elateridae.
According to Dillon and Dillon: "If, by accident or through
human agency, one of these beetles finds itself upon its back,
it has a very singular method of righting itself. The body
is bent upward on a loose hinge between the pro- and mesothorax.
Then, with a sudden snap, it bends itself in the opposite
direction with such force that the whole insect is tossed
several inches into the air, turning over and over as it goes.
Occasionally several trials are necessary, but it is amazing
how frequently the insect will land upon its feet the first
time." The "eyes" are not true eyes, but in fact markings
which might startle birds or other predators into thinking
the beetle was larger or fiercer than it actually is. The
larvae are called wireworms. Adults are usually found beneath
the bark of dead pine trees and are common in the southern
states. Though we do much online searching for identification,
we don't really have a beetle site we visit.
Thanks
for the fast response. Wish I'd know about the flipping part.
Not to be cruel to beetles, but I'd have loved to see it!
I'm sure there will be another time. Maybe I can catch it
on film. I knew they weren't real eyes! I don't think it would
stop our chickens from picking on it. They are young &
into everything as they have just started free ranging. Unfortunately,
the diversity of insects we see at the barn is diminishing
the larger the hens get. At least we only have 7 of them,
they can't eat everything!
Thanks again,
Sandra
Cotalpa
lanigera: Goldsmith Beetle
Re: NH beetle identification??
(06/06/2004) Editor's Note: We lost the
original letter with the description that lead us to guess
the Rose Chafer was the unidentified beetle. Here is the
exchange that followed. We eventually got this photo and
information on the Goldsmith Beetle from a wonderful site.
The Goldsmith beetle is one of the larger Ruteline scarabs
and can be found throughout the Eastern US. The pronotum,
head, and legs of the Goldsmith are a metallic shagreened
gold which unfortunately doesn't photograph well. Larvae
feed inside of rotten logs. Adults feed on the foliage of
some trees including Poplar.
(06/07/2004)
Hi, Thanks Not a rose chafer. Actually looks quite a bit,
but not identical to Plusiotis argenteola Bates from Equador
Do we have anything like that in NH??? I'll try toget my
friend to come take a picture. The dead one I have has darkened
up and is not as bright a yellow as it was alive. I've been
looking for another but since we got cold rain over the
weekend they seem to be hiding again
Thanks again Diane
(06/08/2004)
Thank you for your reply! After nearly a week of looking
I was finally able to ID my beetle, it is a Goldsmith beetle
(cotalpa lanigera) I've lived here in Nh 39 years and never
have I seen this beetle. I must have seen these right after
hatch as there were over 50 of them on the front of the
building that first night. Have only seen 1 in the last
4 days though Are these common? Thanks again.
Diane Richardson Warner, NH
Hi Diane,
The only information I could find in my sources is that
Cotalpa lanigera is about an inch long, yellow with a metallic
luster and that it occurs on or near catalpa trees. Congratulations
on your successful sleuthing. I did just get another report
of a similar beetle from Wisconsin. Daniel
(06/11/2004)
Amazing! We have a HUGE Catalpa here. I've lived in this
location 8 years and never seen this beetle before. Maybe
this is a good year for them. This is the first place I've
lived in Nh with a Catalpa, they are VERY uncommon in this
state. THAT would explain why I've never seen one in years
past I met a person who ses tons of these beetles in CT.
Ct has lots of Catalpa trees Thanks again for your help,
your clues helped me a great deal,
Diane

Male Dung Beetle
We found this cool Beetle dead in our pool. He looks like
some kind of a Scarab Beetle. He has a horn that is not very
visible in the picture. We live in Loganville, Ga (outside
of Atlanta). Unfortunately for the insect population in our
yard, the new pool has become a research lab for my children.
We discover new creatures every day.
Beth Tyson

Hi Beth,
Thank you for the beautiful photo of a male Phanaeus vindex,
a type of scarab from the Dung Beetle group. They are a beautiful
metallic color.
(06/02/2004) Pine Sawyer
Hello, this bug was found boring through the plaster in my
wall last night. What kind of bug is this? It left a hole
about .25" in diameter. I just moved into
a newly constructed home in a newly constructed community
last week. I live in Modesto CA, which is in the Central Valley
and it is an agricultural area. It is possible this bug may
not be from this area at all. It may have come along with
the building materials the builders used. Can you tell from
this picture what type of bug this is and if it is male or
female. I am kind of concerned about whether or
not this bug could of laid eggs inside my wall. If you need
other pictures I will try and take some better ones. This
one that I took is through a plastic zip-lock bag that I have
the bug in. Also, the white powdery stuff on the bug is probaly
the plaster from the wall.
Thanks so much !
Chris

Dear
Chris,
It looks to me like you have a Pine Sawyer, probably Monochamus
titillator. Members of this genus are usually over an inch
in length. The first antennal segment has a scarlike area
near the tip. The antennae of the males are sometimes twice
as long as the body, while females have antennae about as
long as the body. Your specimen looks like a female. They
feed on evergreens, usually on freshly cut logs but they may
sometimes attack living trees. They also bore into felled
trees where the female lays eggs. I'm guessing your specimen
has been boring in the pine of your home since the tree was
cut. You really don't need to worry about being infested at
this point. Sometimes adults may emerge years after the eggs
were laid.
(05/31/2004)
Prionus imbricornus
I found this beetle(?) on my back patio by my sliding glass
door. I am extremely scared of bugs, any type, but I have
never seen anything like this before. I live in South Florida
(Port Saint Lucie) my backyard has a canal with a lot of trees
and bushes. It looks to be around 25 mm in length, it is
redish brown with long antennae that curl around and touch
the ground. Sorry about my description, I try to stay away
and know as little about bugs as possible. The picture may
not be great but I was scared to get too close. I have attached
it. Let me know if you need a better one and I will try my
best.
Thank you, Kim

Hi Kim,
What a beautiful Long Horned Borer you have. The species is
Prionus imbricornis. These are large reddish beetles. Your
species is a male, identified by his longer, thicker antennae.
Larger specimens can reach nearly two inches in body length.
The larvae bore in oak, chestnut and other hardwood trees.
They also live in roots of herbaceous plants.

Caterpillar Hunter
Hi, Bugman. I love your site, although I'm glad I don't
have any of those bugs at my place! The one I found is
bad enough. I found it in my front yard in suburban Chicago. Can
you ID it?
Jerry Palm

Dear Jerry,
You have photographed a dead Caterpillar Hunter, Calosoma
scrutator, one of the Ground Beetles from the family Carabidae.
They are predaceous, feeding on insects and other small
animals. They are especially fond of caterpillars. They
help to control Gypsy Moths and Tent Caterpillars. Adults
will climb trees and they can also fly, often being attracted
to lights in the spring. They are beneficial and should
not be killed.

Look What I Found!
I found this while visiting Vegas a couple of weeks ago. I
don't recall seeing this in ny.

It appears to be a species of Tiger Beetle, Family Cicindelidae.
They are often metallic in color and are fierce hunters. They
run rapidly, often in sandy areas, and they are also quick
fliers. Weiping at the Natural History Museum says "This photo
is not clear enough. It is hard to say it is a tiger beetle
or ground beetle. For me, the body shape is closer to Calosoma
sp. (Carabidae)."

Tiger Beetle: Cicindela campestris
I’m in England and my fiancé and I have found
a bug that we do not know much about, here is a picture of
it, what do you think it is?
Truly Bugged in England,
Virginia and Dave

Dear Virginia and Dave,
You have a Tiger Beetle, Family Cicindelidae. These are fast,
predatory hunters, often irridescent in color. They are also
strong fliers, are often found in sandy locations, and they
capture and kill their prey with powerful sickle-shaped mandibles.
Update (08/22/2006) Hello Lisa Anne and Daniel,
I recently came across your website and I was pleased to see such a
vibrant (and well-done) site. I'm an entomologist and evolutionary
biologist (specializing on the systematics, taxonomy and evolution of
tiger beetles and their close relatives) and I have to say that I'm
impressed with your accuracy rate! It's much, much better than other
comparable sites I've come across over the years. The two of you must
really love insects.
In any case, I noticed that you are open to information from specialists,
so I thought I'd give you a few ID's of species that I came across on your
pages. I was having trouble sleeping, so I went through all of the tiger
beetles, scaratines, etc and checked them out. Here you go:
"(04/11/2004) Tiger Beetle"
This is Cicindela campestris, which is a common and widespread European
tiger beetle. They are beautiful, aren't they?
I'll bookmark your site and check it out when I'm having trouble sleeping
again!

(02/29/2004) Need help with a beetle ID
I came across this beetle today at Cockroach Bay preserve
which is part of Tampa Bay. The reserve is near
Ruskin, Florida and the beetle was in a very sandy area
with some scrub grassland with intermintent wildflowers
and weeds. I know much more about birds and butterflies...but
from what I could gather this may be some sort of stag beetle? It
was good sized...maybe 1.5 inches in length or so. Any input
on this beetle would be great!
Thanks,
Colin Gjervold

Dear
Colin,
I must confess I am intrigued by a place called Cockroach
Bay and I'm not entirely sure I want to visit it. Your photo,
on the other hand, is a new one for us. We checked with
our expert at the Natural History Museum in Los Angeles,
Weiping, who writes: "Sorry to answer you so late. I took
yesterday off for vacation. This image is not a Dorcus parallelus.
You can see five tarsi on the hind leg. I am sure it is
belonging to Carabus sp. (Coleoptera: Carabidae), probably
from Asia.."
(09/06/2004) Ed. Note:
Eric, another of our beetle experts, just wrote in saying:
"The Carabus sp. from Cockroach Bay, FL is actually a species
of Pasimachus. Neat!"
Since we always defer to more knowledgeable experts, we
will include both possibilities.

"Pasimachus possibly, or Carabus species
(02/29/2004) Need help with a beetle ID"
This is most definitely a Pasimachus! (you can omit the exclamation point
and the following if you want to print this, but that beetle is
unequivocally a Pasimachus, not a Carabus. Those two genera are very easy
to separate from even a photograph on the basic of many characters such as
antennal length and form, head width and shape, mandible length/shape,
pronotal shape, etc.) It is Pasimachus marginatus at that, a lovely
species found in Florida and other parts of the Southeast.

Rainbow
Scarab
(02/14/2004) Mystery Beetle with Cute Antennae
Could you identify this beetle that I found in our backyard
this morning? I am attaching a picture - the antennae
are so unusual - and I have to say it - cute. We live
in Pembroke Pines, FL - south Florida just south of Ft. Lauderdale.

Dear Suze,
I must say I admire that you polish your nails before digging
in the dirt. You have a magnificent photograph of a female
Rainbow Scarab, Phanaues vindex, which is relatively common
in Florida. These are scarab beetles further classified as
Dung Beetles or Tumblebugs. The male Rainbow Scarab has a
single long curved horn which arises from his head. These
insects are unusual in that they work in pairs, rolling a
ball of animal dung which is buried with a single egg. The
dung is the food source for the developing grub. They are
important in that they help clear away and break down the
animal excrement, making for a more beautiful environment
as well as more fertile soil. This type of beetle is the scarab
of Egyptian heiroglyphics and jewelry. The ancient Egyptians
were fascinated by the appearance of the beetles rolling a
ball of dung in the sand and likened the ball to the orb of
the sun.
(02/14/2004) my pond
Pleeeease help me....I live in Southern Georgia and I have
a pond in my backyard. Since fall, these strange looking
millipedes(they do have 2 pairs of legs per segment) have
been appearing in my pond. I've never seen any smaller form
of them(they're about finger-length). At first, I figured
they were some hapless terrestrial creature that fell into
the pond, but, upon closer observation, they move about
underwater, and appear to eat dead vegitation....they just
move very slowly. I've googled the subject to death.....
can you possibly help me? If you could solve this mystery
for me, I will have many more peaceful nights....I tend
to obsess on stuff like this. Thank you so much in advance.....

Adel, GA
P.S.- I'm preparing to take some pics of these little buggers,
if they will help, I'd be happy to forward some on to you.
Sorry for the delay....weather hasn't been very conducive
to photography....here's a couple pics....sorry about the
blurriness.

Dear
Adam,
Your image had us confused, so we contacted Weiping at the
Los Angeles Museum of Natural History. He would like to
see a clearer image, but writes: " picture of millipedes
you sent to me is looked like a larva of aquatic beetle.
Unfortunately, the images are too small and not in focus.
Would you think we have a chance to ask that guy to send
me a better image?" There are some large aquatic beetles
that could have laid eggs in your pond. If you could, please
send a clearer photo.
Thanks,
Daniel

We just found this beautiful Devil's Coach Horse while weeding
in our garden. After taking the photo, we released it to
hunt more slugs.

What this bug?
Dear Bugman,
First, congrats on a great site!
Attached are two closeups of a bug, possibly a bed bug, found
when stripping the sheets from our mattress. (We do this every
week, but this is the only 'visitor' we've ever seen). Bug
was not dead, but just lying there waving its little legs
slowly. Could be because we had had a flea infestation (we>lying
there waving its little legs slowly. Could be because we had
had a flea infestation (we>sprayed the house and mattress
with flea spray last year. Any way here it is...

Dear Richard,
I really wasn't positive, so I sought out a true expert, Weiping
at the Museum of Natural History in Los Angeles. Here
is his answer:
"Thank you very much for your image. This is a Thylodrias
larva (Coleoptera: Dermestidae: Thylodrias). It is very common
in Los Angeles area. I collected it many times in our museum.
Hopefully, the information will help you. Sincerely, Weiping"
I can add the Dermestidae is a family of beetles known as
Carpet Beetles or Buffalo Bugs. They are fond of
eating skins, furs, woolen materials and dried animal matter,
and as a family, are the bane of the entomologist since they
can quickly devour a prized insect collection.
Many thanks for the reply - I'm greatly relieved that
its only a carpet beetle, and not something worse! Attached
the second picture, which was of the head/jaws of the grub.
Best Regards, Richard

Dear
Richard,
Thank you for the additional photo. I did find some additional
information for you. The beetle Thylodrias contractus does
not have the typical form of most Carpet Beetles. It is more
elongate with long legs and antennae. I did find an interesting
anecdote in Lutz' book Field Book of Insects. He writes: "In
1908 Mrs. Slosson, the author of such charming stories as
'Fishing Jimmy,' published a description of a strange beetle
that was eating her collection of insects. She playfully called
it 'Ignotus aenigmaticus.' This name was in proper form and
by the rules of the game remained the scientific name of the
beetle until the discovery was made that the beetle was an
introduction from Transcaucasia and had a prior name. It is
now Thylodrias contractus. It eats like a Dermestid but does
not look like one. The female is wingless and the male has
no hind wings." The beetle was originally described in Transcaucasia
by Motschulsky.
Thanks
again Daniel - two further questions,
1. do you have a picture of an adult?
2. Will my bug make it onto your website?
Hi
Richard,
I have your letter ready for posting, but the site is currently
down due to heavy traffic. I was expecting it
to be up today, but still no luck. I know the
site is up on the east coast, since I began getting additional
letters. Check in a day or two. I
have a photo of an adult and will attach it. It
was previously identified only generally, but now there
is an exact species name. Thank you for your
interest.
Daniel
