The description of the reproductive behavior of the dragonfly species Hetaerina auripennisand as body size, spot size on the wings and choice of perch can be interfering with the dynamics of resident and satellitemales were carried out in theBiological Station of Santa Lucia, in the city of Santa Teresa, and an area of pasture in the city of Viana, both in Espírito Santo State (Brazil). Through the scan method with fixed areas, were collected information about the population abundance, distribution of individuals in the study area and behavior. The males employing reproductive strategy were weighed and its spots were measured. The reproductive behavior consists of an encounter, copulationand oviposition. The oviposition is accompanied by mate-guardin. The peak of activity was between 10:00 and 14:00 hours, coinciding with the hottest period of the day. The most frequently observed behavior was perched. This suggests that species belongs to the group of perchers and its dependence on luminosity for the accomplishment of its activities suggests that it is heliothermic. There was no significant relation between body size, spot size with the reproductive strategy employed. Perhaps age is the differential in order to a male becomes resident and the spots serve as a pointer of territory occupation. The type of perch most used by the males were grass stems or leaves, hanging over the river, with a height between 0 to 40cm and a distance from the bank of between 0 to 60 cm. This preference must be related with the ability to visualize females, since they fly to the river for mating and oviposition.
