Range
AZ-FL-NY-MT / ON-QC (3), one of the most commonly coll'ed sp. in Alabama (2)
However, no specimens have been collected from eastern Canada in the last 68 years, consequently, this sp. is likely extirpated from the eastern Canadian fauna. (4)
Season
mostly: May (BG data)
Mar-Jul (in AL) (2)
Food
adults coll'ed from Baptisia, Amorpha, Quercus, plus other plants (5)
Remarks
