Identification
Adult: Upperside of FW is dark on the basal half and lighter on the outer half, with a distinct orange-brown patch at the end of the cell. Male has a costal fold containing yellow scent scales; female has a patch of scent scales on the 7th abdominal segment. b
Habitat
Open woods and barrens for native hosts. Highways, railroad beds, and upland fields for the introduced crown vetch. b
Season
Adults are on wing from late April to early June and again from July to August. There are two generations per year. a
Food
Adult: Feed on nectar from flowers of blackberry, white sweet clover, dogbane, sunflower, crimson clover and probably others. a
Larva: Mainly feed on Baptisia tinctoria, but have also been recorded on Baptisia australis, Lupinus perennis, Thermopsis villosa and Coronilla varia. a
Life Cycle
Males perch in open areas on low shrubs to wait for females. Eggs are deposited singly on the host plant. Fully-grown caterpillars from the second brood hibernate. b
Remarks
The species is rapidly expanding its range and abundance by colonizing plantings of crown vetch along roadways and railroad beds. a
