I believe this is a paper wasp, but I could also be wrong. I do not know what is in her mouth though. So my question is, what is that? It’s cool regardless, but is it food, or larva maybe?

Paper Wasp with Prey

Dear Jamie,
This is indeed a Paper Wasp in the genus
Polistes.  Paper Wasps are solitary wasps and workers set out from the nest to forage for food for the larvae.  Paper Wasps frequently prey upon Caterpillars that they skin in the field, then roll the meat into a ball to more easily transport the food back to the nest.

Unknown Blue Caterpillar

We cannot provide a conclusive identification.  We did locate this very different looking blue caterpillar on BugGuide, and it is unidentified.  We suspect this is some type of Cutworm, the caterpillar of a moth in the family Noctuidae.

Karl Provides an Identification:  White Dotted Prominent Caterpillar
Hello Daniel and Blu caterpillar:
By any chance, was this caterpillar found on an oak tree? If so, I believe it may be White-dotted Prominent moth caterpillar (Notodontidae: Nadata gibbosa). The description according to ‘Caterpillars of Eastern North America’ (Wagner 2005), includes “Sea-green to waxy blue-green, stocky caterpillar, with weakly developed subdorsal stripe; densely salted with white dots. Head enlarged, pale green; mandibles yellow with black tips. Anal plate edged with yellow.” The angle of the shot makes it difficult to make out with certainty, but I think I can make out a hint of yellow at both the front and back end.
Regards, Karl

Thanks Karl,
Before cropping the image, our editorial staff can attest to the leaf in the image being an oak leaf.  This BugGuide posting looks like a perfect match.

Monkey Slug

Dear Wendy,
Though it is atypical looking, the Monkey Slug is actually a caterpillar.  Handle with caution.  Monkey Slugs can sting.

Red Spotted Purple Caterpillar

Dear Curious Tree Owner,
Based on this BugGuide image, we are confident that this is the caterpillar of a Red Spotted Purple, arguably one of the most beautiful North American butterflies.  A single caterpillar is not going to do any serious damage to your apple tree by feeding on leaves, and caterpillars removed from their host plant generally have little chance for survival.  We hope in the future, should you encounter another Red Spotted Purple Caterpillar feeding on your apple tree leaves, you will show a little more tolerance and allow it to remain.  In the event you still feel compelled to remove solitary Red Spotted Purple Caterpillars from your apple tree, BugGuide does provide this list of potential host plants:  “A variety of deciduous trees: willows and poplars (Willow family), cherries, apples and pears (Rose family), birches (Birch family), oaks and beeches (Beech family), Basswood (Linden family) and others. Also recorded from currant and blueberry bushes.”

You’ll be happy to know I found the little guy and placed it back on the tree. 🙂

Wow, we are happy we caught your request early.  For your kindness, we are tagging your submission with the Bug Humanitarian Award.

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). “
