Comprehensive Description

Dialictus pruinosiformis (Crawford)

This is a widespread polylectic species occurring from Alberta, Nebraska, and South Dakota to Texas, New Mexico, Arizona, and southern California. It was by far the most abundant species of Dialictus encountered by us at flowers of Larrea. We captured 184 females and 181 males in May and June at the following localities: Lordsburg, Granite Pass, and 17 miles north of Rodeo, Hidalgo County, New Mexico; 1 and 6 miles north of Portal, Douglas, Tombstone, Naco and Benson, Cochise County, Arizona, and Tucson, Pima County, Arizona. Examples were taken throughout the day (0630–1830). In summer and fall we have also taken this species from Larrea from some of these same localities but in relatively small numbers.
