Perdita marcialis Cockerell 1896

Perdita (Perditella) marcialis Cockerell

This species, like the preceding, was originally collected from Larrea flowers at San Marcial, New Mexico. It ranges from western Texas into Nevada, southern California, and Mexico (Sonora; Coahuila) (Timberlake, 1956). Females fly primarily in September, gathering pollen from Larrea during the second bloom, which follows the summer rains in the eastern portion of its range. However, Timberlake (in litt.) does not regard this species as an oligolege of Larrea because the females have been collected at the flowers of a wide variety of other plants.
