Central Dotted-Blue
Euphilotes centralis

Observation date: July 31, 2020
Submitted by: DeepSkyKelly
Specimen type: Photograph
Observation notes: A type of Buckwheat/Dotted Blue, but Kauffman doesn't include all varieties. Ancilla appears similar, but not the right area. Possibly Central? Not certain that host plants are in the area.
Status: Resident

Coordinator notes: yes, this is one of the Euphilotes species and yes, they are hard to diagnose. the options in your area are limited, however, so I'm going to call it Central Dotted-Blue. This is based on the rather thin orange submargin on the hindwing and the strongly checked fringe on the forewing. Ancilla flies in spring, so that's out. Spalding's Blue has orange on the forewing. Rita Blue is the only other possibility, but I think if you search in that area you should find Eriogonum jamesii var. jamesii, which is the host for Central Doted Blue. Keep looking there, and maybe try to get some upperside shots for this species.
