Afranius Duskywing
Erynnis afranius

Observation date: August 15, 2012
Submitted by: Christian.Nunes
Specimen type: Photograph
Observation notes: This female Duskywing was observed patrolling a pebbly beach in an open area of South Boulder Creek, about 1 mile south of Highway 36. The surrounding habitat is wet meadows/tallgrass prairie/riparian. The Duskywing was observed laying several single eggs on Lupines. A very attractive duskywing, and very boldly marked with silver scales and very bold white spots on the forewing. Hindwing browner with faint pale spots, abdomen not strongly patterned. This duskywing did not strike me as a Afranius/Persius type, probably because most of my observations of such bugs are of male Persius in the spring who are not as boldly patterned. The lack of white fringes, location, egg-laying behavior, and date all point to a female Afranius Duskywing as the most likely identification.

Coordinator notes: I concur with the submitters identification. This species will probably lay eggs on other leguminous plants as well.
