Species text

Distribution
The species is widespread in East Anglia, but otherwise there are few very widely scattered records. It is widespread in north-western and central Europe, with records from France and Switzerland to Hungary.

Habitat and ecology
This species is usually found among wet moss and litter in fens, sometimes in fen carr or in other wet broad-leaved woodland. In Staffordshire, it has been taken in reed-beds and a floating bog (C. Slawson, pers. comm.). Our very limited phenology data indicate a possible peak in adults in late spring/early summer.

Status
The species has been fairly numerous at some sites, but seems to have undergone a substantial decline since the 1970s.

Threats
The most serious threat is from the drainage of fens and wet woodland.

Management and conservation
It is important to maintain the water table in fens and wet woodland. The growth of scrub in fens is probably not as detrimental to this species as to other fenland species.
