Odonatologica, Utrecht, v. 37, n. 3, p. 213-220, Sept. 2008.e- 0375-0183http://repositorio.bc.ufg.br/handle/ri/12091During territorial behaviour, aggressive attacks among heterospecific odon. 3 3 are common and may cause a separation of niches, based on the preferred sites for territorial defence. Here, territorial behaviour and the characteristics of territories in <Jdof Erythrodiplaxmedia, Micrathyriacatenata and M. hesperis are described and their territorial fidelity, capturing and marking of <3 3 are discussed. In all spp. studied, there was a clear distinction among the microhabitats defended as territories. In both Micrathyria spp., 3 3 seem to defend territories with defined resources. In E. media, the defended resources are less evident. Its 3 3 are highlyaggressive and show high territorial fidelity but, apparently, they lose the territory if they stay away from water for at least one day.engAcesso AbertoTerritorial behaviourErythrodiplaxmediaArtigo
