The species limits within this genus are a bit murky, but as a genus they are distinctive. As currently understood, two species are known from Vermont, both of which have a strong preference for goldenrod and related composites.
Genus level ID – Females are all black and relatively nondescript, though can be recognized by the wet pollen held in dense clumps on the hind tibia (a trait shared with Fairy Bees). Males have extensive yellow on the face.
