Abstract
In territorial Odonata, adult male male may use 2 mating tactics that may be genetically or environmentally determined: territoriality and non-territoriality. The non-territorial tactic has been sometimes found to include 2 additional males: sneaking and wandering. The non-territorial male male however, often have lower reproductive success than territorial male male. Studies on various Calopteryx spp. have repeatedly shown that territorial and non-territorial behaviours are conditional mating tactics and that body size does not predict male resource-holding potential and territorial behaviour. Instead, the resource holding potential seems to depend on the amount of male fat resources. Here, both territorial and wandering C virgo male male were collected from a creek in central Finland. It was found that territorial male male were larger and heavier than wandering male male. The data show that the size of the individual may predict the reproductive tactic of some odon. male male to a greater degree than previously thought.
