This morning while picking off azalea sawflies, I found this caterpillar on my “Northern Lights”
azalea . In 15 years of springtime sawfly activity I have never seen a caterpillar like this; on or off an azalea! If you could ID this I would be very grateful.

Humped Green Fruitworm

Humped Green Fruitworm

Dear Joanne,
Your distinctive caterpillar belongs to the Copper Underwing,
Amphipyra pyramidoides, and it is sometimes called a Humped Green Fruitworm, according to BugGuide.  According to BugGuide:  “Larvae are general feeders on leaves of many broadleaf trees and shrubs, including apple, basswood, hawthorn, maple, oak, walnut, raspberry, viburnum, grape, greenbrier (Smilax)” and thanks to your submission, our readers will know to also search for them feeding on Azalea.

Gosh, that was quick!
Thanks so much, he is quite beautiful.
Thanks again.

We found this under a tree. He is about 2 inches long. His underbelly is green with black spots. There are 2 black ‘spikes’ near his rear end. It is almost June here in Albany, NY.

Underwing Caterpillar

Underwing Caterpillar

Dear Abbie,
We believe based on your image and descriptions that this is one of the Underwing Caterpillars in the genus
Catocala, but we are unable to provide you with an exact species.  You may browse through BugGuide to see some similar looking Caterpillars.  Here is a BugGuide image showing a green underside with black spots.

Hi, bugman! Can you help ID this caterpillar? I’ve looked at many pictures today and can’t find it. Thank you!

American Lady Caterpillar

American Lady Caterpillar

Dear Donna,
We had to scroll through quite a few Brush Footed Butterfly Caterpillars before we identified your American Lady Caterpillar,
Vanessa virginiensis, thanks to images posted to BugGuide.  According to BugGuide:  “Larvae feed on Cudweeds, Everlastings and Pussytoes – Gnaphalium, Anaphalis, Antennaria.”

We saw this in Hong Kong on 22 May 2016 in the woodland area by a reservoir. It looked like a caterpillar to us but we could not be sure with the strange patterned head and ‘horns’. Any insight as to what bug this may be and if it is poisonous would be very much appreciated!

Lappet Moth Caterpillar

Lappet Moth Caterpillar

Dear Tai Tam,
This is a Lappet Moth Caterpillar in the family Lasiocampidae.  We found some matching images from China of Caterpillars in the genus
Trabala on FlickR.  Here is another FlickR image.  Some Lappet Moth Caterpillars have urticating or stinging hairs that can cause a skin reaction in sensitive people.

My son took these photos of some interesting invertebrates in our campsite. The vegetation is blackberry, rose, and common hackberry for trees.
We would love to know what species these are or any information you could give us.

Could this be a silver spotted tiger moth caterpillar? I’ve read they are poisonous but the Boy Scout leader said this one wasn’t. It was found near Guerneville, CA. There were coastal redwoods, Douglas firs and Bay Laurels in the area.

Possibly Silver Spotted Tiger Moth Caterpillar

Possibly Silver Spotted Tiger Moth Caterpillar

Dear Toni,
We agree that this might be the Caterpillar of a Silver Spotted Tiger Moth,
Lophocampa argentata, based on this and other BugGuide images.  According to BugGuide:  “Note of Caution: Like several kinds of wooly-bear-type caterpillars, these have venomous, stinging hairs, which can cause a burning sensation and/or a rash in sensitive people- look, but don’t touch!”  We believe the key words are “sensitive people” meaning most folks, including tough, young children, are not affected.
