Chalcedon Checkerspot caterpillar
Hi Lisa Anne and Daniel.
On 4/30 I found three of these caterpillars dining on Wyoming Kittentails west of Casper, WY. After our subsequent 6″ of global warming melted, I located 15 yesterday. Hopefully a chrysalid photo will ensue. Peace, Love and Jerry Garcia,
Thanks for keeping us up on current Wyoming Lepidoptera. The inclusion of the penny is a nice indication of scale. The Chalcedon Checkerspot represents a new caterpillar species for our site.
