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.
Thank you so much.
This helps and clearly is the match.
Feel free to use the photos I sent if they could be helpful for you guys.
