Life stages:
Mating takes place in trees and bushes, and can last up to an hour. The lone female inserts the eggs into plant material, above or below the water surface, or even directly into mud or wet sand along the shore. The eggs overwinter and hatch the following spring. The larvae develop during 2-5 years. The imago-transformation takes place in vegetation low and near the shore.
