Adult habitat & habits

Adults are found foraging far from breeding sites. Usually perch in the sunlight on waterside vegetation.


Breeds in a variety of lentic and slow-flowing wetland habitats e.g. ponds, lakes, bod pools, streams, canals, ditches and rivers. Breeding sites usually consist of large amounts of submerged aquatic vegetation and filamentous algae. Tall grasses, trees and bushes are found quite close to the sites but do not shade them.
