Acmon Blue
Plebejus acmon

Observation date: August 16, 2017
Submitted by: Matthew Lloyd
Specimen type: Photograph
Observation notes: Sunny after rainstorm
Status: Resident
Verified by: A_baldini
Verified date: January 28, 2018
Coordinator notes: Both the Acmon and Lupine blues are heavily concentrated in California, but both are also found farther northeast. However, the Acmon Blue flies much later (into October), while the Lupine Blue’s flight ends in July, so I concur that, based on the date of this sighting, this is actually the Acmon Blue.
