About this speciesRecorded altitude range
0m to 490m
The species is widespread in Wales and much of England, mainly north of the Severn-Thames, with a concentration in East Anglia, and scattered records as far north as central Scotland. It is widespread in north-western and central Europe.
Habitat and ecology
Found in a variety of usually wet habitats such as swamp, fen and marsh, mostly at low altitudes. Adults of both sexes are found in late summer and autumn.
The species is very local, and appears to have suffered major decline. Trend analysis of the continuing decline in area of occupancy over the period 1976 to 2005 indicates a reduction in population size of 40% over a ten year period. However, Wales and the wetlands of eastern England are both relatively less well recorded in recent years.
Drainage of wetland sites for agriculture and forestry.
Management and conservation
Maintain hydrological regime in wetlands where it occurs.
