Wild Indigo Duskywing
Erynnis baptisiae (Forbes, 1936)
Family: Hesperiidae
Subfamily: Pyrginae
Identification: Upperside of forewing 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.
Wing Span: 1 3/8 - 1 5/8 inches (3/5 - 4.1 cm).
Life History: 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.
Flight: Two broods from late April to early June and from July to August.
Caterpillar Hosts: Usually wild indigo (Baptisia tinctoria), but also others including wild blue indigo (B. australis), lupine (Lupinus perennis), false lupine (Thermopsis villosa), and crown vetch (Coronilla varia).
Adult Food: Nectar from flowers of blackberry, white sweet clover, dogbane, sunflower, crimson clover, and probably others.
Habitat: Open woods and barrens for native hosts. Highways, railroad beds, and upland fields for the introduced crown vetch.
Range: Southern New England and southern Ontario west to central Nebraska; south to Georgia, the Gulf Coast, and southcentral Texas. The Wild Indigo duskywing is rapidly expanding its range and abundance by colonizing plantings of crown vetch along roadways and railroad beds. Comments: The Columbine, Wild Indigo, and Persius dusky wings belong to the "Persius complex," a confusing group of very similar butterflies.
Conservation: Not usually required.
NCGR: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.
Management Needs: None reported.
