Black swallowtail chrysalis 

Time to clean the veggie yard. This dude was sheltering underneath the dead cucumber vines.

It’s probably Papilio polyxenes. You can call it a black swallowtail if it’s an adult, or a parsley worm if it’s a larva.  Apparently the color of the chrysalis is highly variable, allowing some of the caterpillars to survive regardless of what they’re overwintering on. It’ll reappear as an adult in the spring. Adults have a high degree of sexual dimorphism: Boys have larger yellow spots on a field of black while girls have some prominent blue patches at the bottom of the hind wing. It’ll be easy to tell once it emerges. This individual spent a month or so munching on a carrot. The carrot suffered, but there were other carrots, so it’s all good. Enough carrots for everybody. And next year, cool butterflies.
