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.

Common Buckeye Caterpillar

Dear Anna,
We tried to identify your caterpillar this weekend, but we were having trouble accessing BugGuide.  We know this is a Brush-Footed Butterfly Caterpillar in the family Nymphalidae, but we needed to determine the species.  We located this identical caterpillar on BugGuide, but alas, it is only identified to the family level.  This BugGuide image leads us to believe you encountered a Common Buckeye Caterpillar.  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.

Common Buckeye Caterpillar

Daniel,
From your resources and referring back to the caterpillar I concur it looks like a Common Buckeye Caterpillar.
I greatly appreciate your assistance.  Wishing you a wonderful day!
Anna
