Perdita (Perdita) salicis sublaeta Cockerell 1896
The flight period of Perdita salicis sublaeta is June to July (Tepedino and Griswold, 1995). Like all members of the tribe Perditini, P. salicis sublaeta 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. It is assumed that P. salicis sublaeta, like other subspecies in the salicis complex, are dependent on willow (Salix sp.) flowers.
It has been recorded in one habitat type within the Columbia Basin, Agricultural.
Perdita salicis sublaeta has been collected only from two sites at Hood River and The Dalles, OR.
