Hi! I’ve been seeing these caterpillars in groups each summer and wonder what they are….I’d like to show them to my preschool class but would like to know what they are first (since they will almost certainly ask!).

Found him through your site, many pages in…Red Humped Caterpillar….Thanks !

Red Humped Caterpillars

Hi Mike,
We are very happy to learn that you were able to self-identify your Red Humped Caterpillars,
Schizura concinna, by browsing through our archives.  As far are requests go, summer is the busiest time of year for us and many requests go unanswered.  More information on the Red Humped Caterpillar is available on BugGuide.

Lobster Caterpillar

Dear Jardine,
This most unusual looking Caterpillar is known as the Lobster Caterpillar,
Stauropus fagi.  It is a caterpillar in the moth family Notodontidae, and the species is found across the Eurasian continent and including the islands of Southern England and Japan.  Here is a link to a photo on the UK Moths website and here are images from the Moths and Butterflies of Europe and North Africa website that show much of the life cycle.  We will be out of the office for a week in mid June, and we do not want our regular readers to suffer any bug withdrawals, so we are preparing your request to post live to our site on June 13.

More Catapillars

These pictures were taken October 23 2010. The catapillar I’m most curious about is the tan one in all three pictures. Me and my sister thought it was super cute. The other catapillar in the third image is less cute and really familiar looking, I think because I’ve seen that type of catapillar a lot growing up. What kind of catapillar is that little tan one? If it’s easy to identify, what is that yellow striped one?
Signature: Thanks a lot, Kelly Bufkin


Hi Kelly,
Your tan caterpillar is a Puss Caterpillar or Asp, the larva of the Southern Flannel Moth,
Megalopyge opercularis.  Handle the Asp with care as it is a stinging caterpillar.  The yellow striped caterpillar appears to be one of the Prominent Caterpillars, possibly Datana contracta based on images posted to BugGuide.

Hello there,
Three of these caterpillar/larva are on my deck. I have never seen anything like them before. I took the picture. Also, what is that reddish orange part that isn’t the head? Hope you can help.

Red Humped Caterpillar

Dear MaryLynn,
Knowing where to begin a search is often very helpful.  We thought your caterpillar resembled a Prominent Moth Caterpillar in the family Notodontidae, and we were quickly rewarded while searching BugGuide with the Red Humped Caterpillar,
Schizura concinna, a species found coast to coast in North America.  The “reddish orange part that is not the head” is the hump, though we cannot say for certain what its purpose is.

Wow! You guys are sure prompt. Many thanks, Daniel.

I’m looking for the identity of these caterpillars. They were feeding on a blueberry bush. They fed in bunches at the end of a branch and raised their head and tail when disturbed. Seen in mid- August.

Drexel's Datana Caterpillars

Dear Angela,
The defensive posture you have described and photographed is consistent with the Prominent Caterpillars in the genus
Datana, and the food plant and the coloration indicate that your specimens are Drexel’s Datana, Datana drexelii, which is described on BugGuide.

Thank you!!  I’ve been trying to find out what tese are ever since I first saw them!  I really appreciate your help.

black and white stripped caterpillar
December 24, 2009
I found these acrobatic caterpillars on my George Tabor Azaleas I believe it was in September. Their black and white stripes were quite different. It was their red head and legs and tail that caught my attention. No major harm was done to my azaleas. Could these be the caterpillars for a zebra swallowtail?

Azalea Caterpillars

Azalea Caterpillars

Hi again Leslie,
These are Prominent Moth Caterpillars in the genus Datana.  It is probably the Azalea Caterpillar, Datana major, which feeds on Azalea and a few other plants including red oak, apple and blueberry.  The species is well represented on BugGuide which indicates:  “female lays masses of 80-100 eggs on underside of leaf in late spring or early summer; first instar larvae feed gregariously, skeletonizing leaves of hostplant; older larvae eat entire leaves; usually one generation per year, with partial second generation in the south; overwinters as a pupa in a cell in the soil.
“  This posture is typical of caterpillars in the genus Datana.
