I caught a fast moving pipevine swallowtail, Battus philenor, laying eggs on my woolly pipevine, Aristolochia tomentosa.
Lots of eggs.
Some of the eggs were laid a few days earlier and tiny caterpillars are beginning to eat the pipevine leaves. Some people would be going for the insecticide to kill the caterpillars, but not me. I am not concerned about the caterpillars eating the leaves because I planted the pipevine as host plant (food source) for pipevine swallowtail caterpillars.
Woolly pipevine is also known as woolly Dutchman's pipe because of the hairy appearance of the vine's leaves and stems and the pipe shape of the flowers. Plants of the Aristolochia family are the sole food source for pipevine swallowtail caterpillars.
