Variegated Fritillary Caterpillar

Dear Sharon,
We believe this is a Variegated Fritillary Caterpillar and according to BugGuide:  “Larvae feed on Violets & Pansy (
Viola), Flax (Linum), Passion Vine (Passiflora), Damiana (Turnera), Moonseed (Menispermum), Mayapple (Podophyllum), Stonecrop (Sedum), Purslane (Portulaca) and others. Adults are fond of flowers, and especially seem to like Thistles and yellow Composites. They also frequently visit damp ground.”

My 6 year old son found this catarpillar outside and we want to know what kind it is. Is it venomous? What type of tree leaves does it eat? And what kind of butterfly will it become? Thanks so much!

Common Buckeye Caterpillar

Dear Momma of Boys,
This is a Common Buckeye Caterpillar,
Junonia coenia, and it is perfectly harmless.  The Common Buckeye is a beautiful spotted butterfly.  BugGuide lists host plants as “Plants from the snapdragon family including snapdragon (Antirrhinum), toadflax (Linaria), and Gerardia; the plantain family including plantains (Plantago); and the acanthus family including ruellia (Ruellia nodiflora).”  Butterfly Fun Facts lists Mexican Petunia (Ruellia species) as a host plant.

Your letter to the bugman:  I work in a landscape yard so naturally I see a lot of critters. This one was new for me. We have a plant called helichrysum icicles that were covered in little busted open, poop filled,fuzzy tents and these caterpillars wandering aimlessly on the plants. Best I can tell, they are Painted Lady, but I am uncertain.

American Lady Caterpillar

Dear Karin,
In our opinion, you have the correct genus but not the correct species.  We believe this is an American Lady Caterpillar,
Vanessa virginiensis, based on this BugGuide image, and not a Painted Lady Caterpillar, Vanessa cardui, which is also pictured on BugGuide.

Thank you so much! They didn’t seem to be doing anything destructive, thankfully.
