Echo Azure
Celastrina echo

Observation date: April 27, 2020
Submitted by: pnesterenko
Specimen type: Photograph
Observation notes: Almost went with Boisduval's Blue (Plebejus icarioides) as I frequently see that species nearby.
Status: Resident
Verified by: A_baldini
Verified date: April 29, 2020
Coordinator notes: Although Silvery Blues do fly this early, this is actually an Echo Azure, another species of early-flying blue. Look closely at the markings on the underside, and you’ll see that they’re quite different from those of the Silvery Blue.
