General Description

The duskywing skippers (genus Erynnis) can be a challenge to identify, particularly in prairie habitat where all three species may occur together. The Dreamy Duskywing can be separated from the other two species by the white spot near the forewing tip: icelus has either only one spot or none at all, while the other two duskywings (E. afranius and E. persius) have at least two (more often three or four) spots. The Dreamy Duskywing is also slightly smaller on average, with a wingspan of 25 to 30 mm. the forewing apex is more blunt in shape, giving icelus a more squared-off appearance than the other two duskywings.
