Abstract

Perdita octomaculata nested in sand quarries in New York State. Females nested singly in bare, usually sloping sand bluffs. Horizontal subsurface burrows in loose sand led to sloping main burrows that reached cells at the ends of 1-9 cm long, horizontal, lateral burrows at depths of 21-88 cm. Marked females occupied nests from 1 to 9 days (median = 1) and made up to 5 different nests each. Foraging behavior on Solidago is briefly described. The mature larva and pupa are described and illustrated. The nesting biologies and immature stages of the other well-studied species in the octomaculata species group of the subgenus Perdita, P. nuda and P. maculigera maculipennis, are compared and strategies of the species group for nesting in loose sand are hypothesized. The solitary nests of P. halictoides in Florida are briefly described, as are the mature larva and pupa.
