Abstract
The present investigation explains the reproductive behavior i.e. territory, copulation and oviposition for Brachythemis contaminata which was carried out for a year between June 2013 to April 2014. The male plays significant role in mating as competing for fertilization by attracting females, but in odonates female also actively involving as taking mating decision, male selection and activities during tandem formation. Territory of mating male is well marked of about 2 to 3 meter in diameter and is at the same place of oviposition. Male prefer territory attachment as strategies of mutual avoidance which reduces energy spent in inter-male fight. Male-females are generally in group with high male ratio till evening and male become more careful and aggressive in evening for his territory. When receptive female visits to mate in male’s territory she chooses the fittest male for mating. Male shows aggressiveness, wing vibration, abdominal display, chasing to competitor are the main events use for mating strategies. Copulation takes place in air for only few seconds and mating success for territorial male is high.
