Males of Lasioglossum zephyrum demonstrated that females have odors which are characteristic of individuals. In a sequence of presentations of odors of individual females, male response toward odor of a given female decreased with time. However, renewed response resulted from the presentation of odor of another female. Furthermore males of this species are capable of "remembering" individual odors of females in nature, since in the laboratory they remained habituated to odors of individual females for at least 60-135 min.
