Male Pachydiplax longipennis show territorial behavior which is expressed by displacement of conspecific males from a defended area about a perch site. The behavior is characterized by a threat display given on the perch site as well as in flight. Adult male recognition is achieved in part by the bluishwhite pruinescence on the male's abdominal surface. Female recognition is made in part by the series of yellow spots on the dark background of the abdominal surface. Teneral males, apparently due to their immature color pattern which is similar to that of the female, are recognized as females by mature males. No male courtship was observed. All breeding and oviposition occurs in the territory and the male guards the female while she is ovipositing.
