Black Swallowtail

This is the second year in a row I have grown dill and with the dill come the Black Swallowtail Larvae. This is one of their primary sources of food. I actually watch them grow by the minute with how much and fast they eat. When touched they emit a foul odor and orange antennae stick out of their heads. They do some damage but I leave them alone. They eventually morph into this butterfly. "What a wonder of nature" Feeding on my Ligularia in Connecticut
