I found this little buckeye butterfly caterpillar in the ragged remains of my almost-dormant perennial snapdragons today. They love the snaps and verbena bonariensis. Last summer I had several dozen buckeye caterpillars but this summer I didn't see any. However, I could have missed them because I wasn't really looking. I hope this little guy has a parka handy. I'm very thankful that it survived all the transplanting I've done and that there are still leaves on the snapdragon.
Buckeye butterflies (junonia coenia) are native to much of the warmer climates of the United States and can overwinter as a caterpillar, chrysalis, or butterfly. Their host foods include perennial snapdragons (antirrhinum), verebena bonariensis, toadflax (linaria), plantains, and ruellia. With the exception of the plantains, all of their host foods can be found in my garden, but I usually find them in my verbena and snaps.
These perennial snapdragons are champions of heat, drought, and full sun. They form a bushy mound about a foot wide and a foot high. I purchased mine at Plant Delights Nursery since I couldn't find them locally.
Buckeyes are small butterflies that seem to enjoy a wide variety of nectar producing plants. They were quite fond of my annual 'Buddy' gomphrena this summer.
