American Black Swallowtail Papilio polyxenes asterias 

We hardly ever have eggs available. There are some ready immediately.

It is immediately evident from looking at this striking black Swallowtail that it has a lot in common with the British and European Swallowtails and it is indeed so closely related that it will hybridise with either one.

The larvae feed on Fennel and may take Carrot leaves and those of other Umbelliferae. Keep the eggs in a plastic box as described in the introduction to Plastic Rearing Containers. Transfer young larvae with an artist's brush to fresh, high quality foodplant, preferably growing.

The pupae overwinter but may produce a partial second brood of butterflies in late summer.
