Baltimore Checkerspot Caterpillar

Dear Randall,
We were able to identify your Baltimore Checkerspot Caterpillar,
Euphydryas phaeton, thanks to images posted to BugGuide.  According to BugGuide:  “The primary larval food source is turtlehead (Chelone glabra), although recent studies have shown that the caterpillars will eat a larger variety of plant species including English plantain (Plantago lanceolata), a common yard weed.”  The adult Baltimore Checkerspot is a very lovely butterfly.
