Dotted Blue complex (Euphilotes enoptes)

Similar species. Pyle (2002) distinguishes between the Pacific Dotted (E. enoptes) which feeds on Eriogonum elatum and Rocky Mountain Dotted (E. ancilla, aka E. enoptes ancilla) which feeds on Eriogonum compositum. He suggests that range maps are likely inaccurate due to confusion over these two. There is also a chance for confusion with the Square-Spotted Blue (E. battoides). Andy Warren (2005) treats E. e. columbiae as a separate species.
