Parsleyworm Caterpiller

This Parsleyworm is feeding on dill in my garden. They also like to dine on parsley, celery, fennel, and other plants in the carrot family Apiaceae. After he or she is done dinning for 3-4 weeks they will then form a pupa in a grayish chrysalis. After roughly two weeks an adult Black Swallowtail Butterfly will emerge. This butterfly will feed on nectar, mate, and lay eggs to produce more Parsleyworm caterpillers. In the midwest there is generally two hatchings of Black Swallowtail Butterflies. When fall comes the caterpillers form a chrysalis and stay in their chrysalis until spring of the next year, when they start this process all over again. I will be watching for the Black Swallowtail Butterflies when they hatch and post a photo at that time.
