摘要: The behavioral ecology of Plathemis lydia (Drury) (Odonata: Anisoptera) was studied at several ponds in northern New York State. Males and females utilized restricted areas the ponds. Female occurrence highest during a short time period each day, while males occurred throughout most day. Thus, were considered to be highly predictable space. returned daily traditional area which primarily for mating. Ali on one interacted aggressively with other establish dominance hierarchy.
