pls identify this ootheca(?)
March 13, 2010
I’ve been assuming/hoping this is a mantid ootheca, but it doesn’t look like any ootheca I’ve seen on the web. Is it a mantid ootheca or some less desirable creature? Found on a Japanese Maple tree in zip 43206. I want to hatch the mantids indoors to release in my garden…
Thanks! Tony

Bagworm
Hi Tony,
Theoretically, this is the cocoon of a Bagworm, a moth in the family Psychidae. You may see additional examples and some species identifications on BugGuide. We wrote theoretically earlier because the female Bagworm is wingless, and she only crawls out of her cocoon to mate. After mating, she returns to the cocoon and lays her eggs, so the cocoon may become an oothica of sorts.
Thanks Daniel! I guess I knew it wasn’t what I wanted or I wouldn’t have asked!? At least now I know that I really do need to order a mantid oothica. You guys offer a great service to us laymen! Thanks again.

Hello, my name Reuben and i am 8. I found this insect on a wattle tree. We live in Queensland Australia. Can you tell us about it??? Me and my brothers love your website.

Acacia Leaf Beetle Larva
Hi Reuben,
Thanks for your kind words. This is the larva of a Leaf Beetle in the family Chrysomelidae. Though your example is definitely not the Silver Wattle Leaf Beetle pictured on the Brisbane Insect website, it does have some similarities. We eventually located the Acacia Leaf Beetle, Dicranosterna picea, also on the Brisbane Insect Website, and the larva appears to be a good match.

venomous
February 26, 2010
things that are VENOMOUS are more then once referred to on this site as poisonous there is a big difference between the two.
G. Davisson
Dear G. Davisson
Merriam-Webster.com defines Poisonous as “1 : destructive, harmful 2 : having the properties or effects of poison : venomous 3 : spiteful, malicious.” Merriam=Webster.com defines Venomous as “1 : full of venom: as a : poisonous, envenomed b : noxious, pernicious <expose a venomous dope ring — Don Porter> c : spiteful, malevolent <venomous criticism> 2 : having a venom-producing gland and able to inflict a poisoned wound <venomous snakes>.” Since that bastion for defining the English language uses the two words to define one another and indicates that they are interchangeable, we don’t feel we are entirely incorrect in our usage, though there might be a subtle difference that we should consider. The bite of a Brown Recluse Spider would be venomous, while poisoning would occur following the ingestion of a Toxic Milkweed Grasshopper. Rather than just providing a blanket statement chastising our language usage, can you please cite some concrete examples of the adjective usage that you find offensive? That way we can consider them more closely. Even better, can you provide the source for the definition that creates a solid distinction for the proper and incorrect usages of the two terms?

No clue what this is, found at school computer lab, should i be scared?
February 21, 2010
Hi my friend and I saw this bug at the computer lab at our school crawling up on the wall, we have no clue what it is. It looked black and gray as you can tell it has a lot of legs. Please help! We go to college on a mountain and we swear they have some undiscovered species of insects roaming around.

House Centipede
Hi Sam,
The House Centipede is not only harmless, it is actually beneficial since it will eat potentially problematic household intruders.

Hello!
I just wanted to extend a thanks to all you who make “What’s That Bug” possible. It’s really an excellent site and I often find myself perusing it just to feed my amateur entomolgist’s appetite! I noticed the Nasty Reader’s Section you have and was both amazed by the breath-taking idiocy of some of the readers featured there and amused by your responses.
So thanks again, for all you hard work on an excellent site!

Hi Nate,
Thanks for your words of encouragement.
Identify unknown insect possibly beetle

Wehave thousands of these bugs on our screened porch, in the roof ridge and attic vents, outside walls, kitchen, bedrooms, living room, etc. They are very slow moving at any time of year and appear harmless to people. Mainly s curiosity.

Brown Marmorated Stink Bugs
Hi Bob,
You have Brown Marmorated Stink Bugs, Halyomorpha halys, a species that was introduced from Asia where it is an agricultural pest. According to BugGuide: “They sometimes invade homes in the winter by the hundreds!“ Here is a link to a fact sheet on Invasive.org that shows the entire life cycle.
Thanks a million Dan, you guys are the best – I don’t care what anybody else says about you. You are extremely timely, accurate and thorough and a fantastic service for us laypeople annoyed by invasive bugs.
I have read some of the literature you pointed to and it seems as though the synthetic pyrethroid insecticides indicated are not very effective due to sunlight deactivation in a few days. I think BMSBs may be sensitive to Spectracide Bug Stop indoor plus outdoor insect killer which I have used during the past six months to reduce spiders, centipedes, thousand leggers , etc. which have profusely invaded our daylight basement by spraying all windows and doors perimeters as well as spraying the floor wall corners and joist wall corners throughout the basement.
I did notice masses of these BMSBs at the attic peak vents and ridge vents when I was exterior prepping and painting this past September/October. I will try spraying these points from the outside and inside as well as the porch and attic. I have also gotten BAYER Advanced Home Pest Control Indoor & Outdoor Insect killer which is supposed to have a 9 month residual – to keep killing throughout the fall and winter – however, I don’t see stink bugs listed on the label of either of these pesticides. It seems as though there are numerous dead adult BMSBs on the basement floor and I thought the pesticide was the cause of mortality but it could have possibly just been their lifecycle.
I used to have the philosophy of not killing indoor bugs – especially spiders – since I felt the spiders would control all the others but the wife couldn’t stand all the creepy crawlies anymore and is deathly afraid of spiders so we took control action which has been extremely effective in the basement so far.
Best regards, Bob
Kids science book
February 15, 2010
Hello, I’m writing a couple of science books for children but the publishers want them to be international. One of the experiments is about garden science and looking at what bugs you can find in your soil, through a funnel shining a light on top. I need to come up with a list of international bugs and wondered if you could help? Many thanks indeed,
Lisa
International!
Hi Lisa,
Please describe the experiment more thoroughly as it doesn’t make sense to us how the funnel and light are used. One international subterranean dweller is a Mole Cricket, but we are uncertain how your trap would work in finding the mole cricket. It would be much easier if we just provided you with a list of potential soil dwellers.
Daniel
Thanks so much for getting back to me! It’s like a Berlese funnel experiment. A list of potential soil dwellers would be absolutely perfect! And if you happened to know which were most widespread, all the better, but I realise that is very hard to ascertain sometimes,
All my very best wishes,
Lisa
Comment from Australia
Hi guys,
Congratulations on being near the end with the book project. … As an aside, I noticed the letter about the light and the funnel. One method of trapping insects is to bury a bottle with a funnel so that the lip of the funnel is at ground level. A light is suspended above it and ground dwellers walk to the light and fall into the funnel. Hope that sheds some light on it

I’m traveling to Bhutan and am looking for insect field guides and was hoping to get some recommendations.
Thanks in advance.

Dangerous , deadly or painful bugs.
February 11, 2010
I was looking for a way to identify a few bugs in my home. It would be helpful if the search included criteria such as how many legs , wings etc.
Also , I can’t understand why you would include an unnecessary carnage page and not have a page dedicated to which insects known to man actually are dangerous , deadly or have a painful sting or bite even if they are not venomous.
It renders the UC page pointless if you don’t list all the bugs which aren’t unnecessarily killed.
Sure I love living things , but not if they bite or crawl into my ear when I’m sleeping.
So please include a list of those bugs . It’s very hard to find the information elsewhere .
TM
Hi TM,
We just might take you up on this suggestion. We can call the page Justifiable Homicide. We would definitely put Argentine Ants and Aphids at the top of the list. Some creatures like Black Widows might be dangerous, but we could never include them on a Justifiable Insecticide, though they might be sub-categorized on that page.
Lack of any kind of insect (Alaska)
February 5, 2010
We are here temporarily (Fairbanks AK), and I have not seen one insect of any kind in three months! It’s really creepy! Not even a house related “bug”. Just one spiderweb. Now even dust bunnies make me jump, as I’m like someone waiting for a balloon to pop. I suppose I’ll pay for this later when the mosquitoes hatch, but it’s sure fun to look at your website for now….
J Sugino
Dear J,
We are sorry to hear about the dearth of insects in Alaska, and your subsequent withdrawals, but it is currently winter there. We are happy to hear you are getting some pleasure from our website, and we assure you that come spring, you will undoubtedly be graced with some Alaskan insect wildlife.

six legged worm thing?
February 2, 2010
Im not sure what this thing is it was found in my back yard and its a little over 2 inches long and fairly thick it has fuzz on it and it must burrow because when i put it in the grass again it starting moving down. when its flipped right side up it roles onto its back and begins to wiggle normally. it has a dark colored head not sure if its dark red but it does have pincers and there’s something inside its tail maybe a sack its black and white. I’m not to fond of insects but i;d like to know what this is because Ive never seen one before.

Crawly-Back
Hi Luis,
This is the larva of a Green Fruit Beetle, Cotinus mutabilis. They are often found in compost piles and they are known as Crawly-Backs. The beautiful green adults fly in August, and because they feed on fruit, they are sometimes called Figeaters.
