Black Swallowtail

            Papilio polyxenes asterius -- 5th instar

In western Nebraska the western Anise Swallowtail's -- Papilio zelicaon -- territory overlaps that of the eastern Black Swallowtail. Both species share the same host plant and the larvae are indistinguishable. I went looking for zelicaon and ended up with polyxenes.

The host plant is Slender Wildparsley -- Musineon tenuifolium.

This species has fluorished most likely due to the fact it loves cultivated dill, fennel, parsley and rue. One wonders how many females actually find a native host plant. This photo documents one such native plant that grows wild in Co., Wy., SD. & Ne.
