Uncas Skipper
Hesperia uncas

Observation date: June 01, 2020
Submitted by: Cascade Colors
Specimen type: Photograph
Observation notes: Many were feeding, all on what I believe was Western Wallflower blooms.
Status: Resident
Verified by: A_baldini
Verified date: June 05, 2020
Coordinator notes: These are Uncas Skippers, Hesperia uncas. Western Branded Skippers fly much later (Aug. to Sep.), and the Nevada Skipper has more separated white spots on the ventral hindwing rather than a continuous v-shape as in the Uncas. Uncas usually have their best flight in June, though they can also be found later or slightly earlier.
