Identification
The very distinct dark spots on the wing and the dark postclypeus are diagnostic. (E.L. Mockford, pers. comm. to =v=)

But note comment on briggsi info. page: "E. briggsi and E. californicus are difficult to distinguish except on a slide even when you have them on hand, and photos are much more difficult. Apparently now, E. briggsi has become established in spots along the east coast, so that both species occur now on both coasts. Males tend to be somewhat variable in color. -E.L. Mockford, pers. comm. to =v= 31.v.2013".
