Hedgerow Hairstreak
Satyrium saepium

Observation date: July 12, 2018
Submitted by: Christian.Nunes
Specimen type: Photograph
Observation notes: One of several very fresh individuals. They were found flying below the summit of the ridge on a north-facing slope among Douglas-Fir and Ponderosa Pine trees. This one preferred to land on a dead stump and on patches of kinnickinnick. It was warm and sunny out, so these hairstreaks were flying very quickly and were difficult to approach.
Status: Resident

Coordinator notes: Definitely the Hedgerow Hairstreak, just about the most plainly marked/colored hairstreak in Colorado. The "flying very quickly" sounds like typical Satyrium hairstreak behavior; sometimes several individuals even form tiny "tornadoes" (a type of pre-mating behavior) that are impossible to follow with the naked eye!
