Queen Alexandra's Sulphur
Colias alexandra

Observation date: June 17, 2019
Submitted by: Paul Prappas
Specimen type: Photograph
Observation notes: Lone sulphur among many Western Whites. When I first saw the spotting on the ventral side, I ruled out Queen Alexandra's, yet the HW cell spot and green scaling as well as the wing shape all pointed to QA. Apparently, this species can show some ventral spotting, so that helped sway me on the ID.
