Genus Perdita
Numbers
Nearctica lists almost 550 species.
About 700 species according to John Ascher.
Identification
Scopal hairs in females are often quite sparse, so sparse that they would be considered indicative of a male in other species. Females appear to always have a relatively long scape, similar to Lasioglossum and the males with a quite short scape.
Range
North America and Central America.
Remarks
Perdita females have short scopal hairs because they use moisture to stick the large pollen load to the hind tibia; males have yellow maculations of T5.
