Identification:
Similar species:
Life stages:
The, prolonged, mating takes place in the vegetation near the water course. The solo flying female descends and inserts the eggs into sand or mud at shallow waters. The eggs hatch after a few weeks, and the larvae live buried in the bottom material or on the bottom when needed. The larvae develop during 3-5 years. The imago-transformation takes place near the water and low on the vegetation.
Distribution:
(?):Altitude is often taken from a specific localized resource, why the true entire range very likely is wider.
Most of Europe; absent most of Ireland, C Norway and the northern Scandinavian peninsula. Also absent east Mediterranean region, the Balkans and the Black Sea region. Also present NW Africa and patchily through Russia to the Ural mountains.
Habitat:
Behavior:
Females tend to hide before mating.
