Abstract

Information on the nesting biology is reported for Caupolicana ocellata Michener (Colletidae: Diphaglossinae) and Martinapis luteicornis (Cockerell) (Anthophoridae: Eucerini). These species collect pollen from Psorothamnus scoparius (Gray) Rydberg (Leguminosae). Nests of both species were found near one another close to the Willcox playa in southeastern Arizona. Details of nest architecture, provisioning and a description of the egg of Martinapis are presented. This information is compared and contrasted with related bees. Also provided is casual information on the early matinal flight periods of the two species and of Caupolicana yarrowi (Cresson).
