Abstract

Male Lasioglossum (Dialictus) zephyrum in the field are attracted to models impregnated with the odor of virgin females. The number of males responding increases with increasing odor concentration. Once a male has contacted a model, its attractiveness to other males is reduced, suggesting that the male may contribute an antiaphrodisiac cue so that other males avoid mated females.
