FIELD STUDY OF FOCAL INDIVIDUALS

Individual damselflies (i.e. males, blue female andromorphs, green female heteromorsphs) were caught, marked and the observed for as long as possible. Harassments by males were noted as was the behavior used by females to elude males. Perch heights were noted for a subset of individuals. Prey capture and predation on individuals were also noted.
