Looking to find out what type of caterpillar this is your and what they typically eat. We’re in coastal San Diego and it’s mid July. Something has eaten my tomatoes but not sure it’s the caterpillar or birds.

Tobacco Hornworm

Dear Hanna,
Though it is commonly called a Tobacco Hornworm, this caterpillar is frequently found feeding on tomato plants.  Here is a BugGuidetobacc image for comparison.

Carrot Seed Caterpillar on Dill

We have not had any luck identifying your caterpillar.  The only caterpillars we can find associated with dill in Eastern North America is the Black Swallowtail Caterpillar, and your caterpillar is most definitely not a Black Swallowtail Caterpillar.  Your caterpillar does remind us of the Sophora Worm, but they feed on legumes and dill is not a legume.  Perhaps one of our readers will recognize this caterpillar.

Ive talked to another girl I know and she said its called a purple carrot seed caterpillar/moth.  Ever heard of those?

The Carrot Seed Caterpillar pictured on BugGuide does appear correct.  According to BugGuide:  “The larvae feed on umbellifers, particularly wild carrot” and “‘Recently introduced into North America (first specimen reported from 2002) and now known from Illinois, Indiana, Michigan and Wisconsin’. * (information from – Moth Photographers Group). “

My husband found this on the garage floor today (July 14). He picked it up with a paper towel and it seemed to grab on to it. While trying to get pictures, he had a hard time separating it from his glove as it was holding on to that as well. I scoured the internet and cannot find anything remotely close to its image. I’m hoping you can help to identify it! Thank you for your time.

American Lappet Moth Caterpillar

Dear CuriousGeorge,
Your image of an American Lappet Moth Caterpillar,
Phyllodesma americana, in its threat position is quite wonderful.  Here is an image on BugGuide of an individual’s ventral surface that shows the same markings as your individual, and this BugGuide image illustrates the threat position.  The BugGuide description is:  “Larva: body with blue, black/gray, white, and orange on the back, and densely hairy lobes (lappets) along sides; top of eighth abdominal segment with unpaired hump; when stretched out or alarmed, exposes bright orange band across top of second and third thoracic segments”

My sister found this giant caterpillar and I’ve since been curious as I can’t identify which species it belongs to.

Christmas Caterpillar

This is a Christmas Caterpillar or Pine Emperor Moth Caterpillar, Nudaurelia cytherea.  According to Featured Creature:  “The caterpillar of the Pine Emperor Moth (Nudaurelia cytherea) isn’t exactly dressed for a glamorous ball but instead an ugly Christmas sweater party! It’s definitely looking festive with that big, fat, red santa-inspired body dotted with lime green, lemon, and light blue spots. I think the course gray hairs really add an extra touch of ‘ugly’ to the ugly Christmas sweater caterpillar feel, don’t you?”

We saw this bug on July 11th at the North Carolina Zoological Park in Ashboro, North Carolina. My 22 year old daughter took a video and showed it to an employee who said she had never seen anything like it and that it moved like a caterpillar

Monkey Slug

Dear LeeAnne,
Though it does not look like other caterpillars, this Monkey Slug really is a caterpillar.  Handle with caution though, the Monkey Slug is capable of stinging.

Can you help please?
I was wild camping in a wood near Princes Risborough, Hertfordshire last night and this beast fell out of a tree onto my mate’s arm.
Do you know what it is?
Incase this isn’t clear from the pics, this is his wrist, so the bug was about 6cm long. It seemed to rear up??
Many thanks

Lobster Caterpillar

Dear Ben,
Though it looks nothing like a typical Caterpillar, this Lobster Caterpillar is actually the immature form of a Moth in the family Notodontidae.  According to UK Moths:  “This unassuming species gets its English name not from the adult moth, but from the remarkable crustacean-like appearance of the caterpillar.”

Dear Daniel,
Thankyou so much for your reply. Was it unusual to find in the UK/Princes Risborough? I’ve Googled and seen a Japanese one that looks very similar
Best regards
Dear Ben,
The Lobster Caterpillar ranges throughout Eurasia, from England to Japan.  There are several British sites that include the
Lobster Moth Caterpillar, including UK Safari.
