Swallowtail Butterfly Caterpillar

This year I have found BOTH a Monarch and a Swallowtail butterfly caterpillar.

I could not figure out why the Monarch mother laid her eggs on some parsley that I nearly put in the blender to make vegetable juice, before noticing the caterpillar. Lucky for both of us, I did not have extra protein in my juice!

I finally did research and realized this was NOT a Monarch, but that the dill and parsley I had planted had succeeded in attracting a Swallowtail. The next day I found a Monarch.

I had them both for about a week when they spun threads to hang their chrysalli, and then shed their skins. The Swallowtail matches its color to the surroundings, in this case an unbleached coffee filter!
