Note.

This native species is associated with witch hazel, Hamamelis virginiana L. ( Hamamelidaceae ) ( Clark 1987). Adults emerging from hibernation are active from mid-May to early July, and those from the current-year generation emerge from mid-August to early September and then hibernate until the following spring ( DeSteven 1981).
