The majority of African species breed in slow-flowing reedy streams or lakes, pools and swamps which have plenty of reeds or fringe vegetation. The adults generally take short flights from one perch to another or back to one particular perch if, perhaps, it is more suitable in strength, height or position than other reeds. If the resting place commands a narrow channel of water or if it is on a prominent stem amongst fringe vegetation on the bank of a river the adult will often exhibit territorial claim, chasing off other males approaching the perch.
