Edge of the Prairiethe sand prairies and savannas of the Chicago region

    Pterourus troilus troilus
    Spicebush Swallowtail Butterfly

This mating pair of Spicebush Swallowtails was photographed hanging from a big bluestem stalk in late summer. The female is the one hanging onto the grass, and presumably the active flight parnter as well.

Spicebush Swallowtail Butterflies mating

Spicebush (Lindera benzoin) grows in sand country but isn't common; the population of Spicebush Swallowtails in this area probably uses the abundant sassafras trees as its primary larval host plant.
