taxonomic status

Perdita (Perdita) accepta Timberlake 1958

life history

The flight period of Perdita accepta is July to August (Tepedino and Griswold, 1995). Like all members of the tribe Perditini, P. accepta nests in the ground. (Perdita nests differ from the majority of andrenid nests in that the cells are unlined or only partially lined.) Nearly all species of the tribe Perditini are specialist foragers. P. accepta is likely dependent on flowers in the family Compositae.

It has been recorded in one habitat type within the Columbia Basin, Ponderosa pinegrassland.

distribution

Perdita accepta has been collected only once, at Tumalo in Deschutes County, OR.

threats and conservation needs

Threats to this species are currently unknown.

Conservation efforts should ensure that suitable (unknown) flowering plants persist and that appropriate nesting substrate remains. Little is known of the biology of this species. Studies of both the nesting and foraging habits would be valuable.
