About this species

Recorded altitude range
0m to 800m

Species text

The species is widespread in Wales, northern England and north-western Scotland, though the majority of recent records are from Scotland. In the south and east there are very few recent records. It is a Palaearctic species, widespread in most of north-western and central Europe.

Habitat and ecology
A. crassiceps occurs in a variety of habitats including moss, grass, straw, litter, tideline debris and heathland, but in rather damper conditions than those favoured by A. humilis. On heathland in Dorset males were found to be active from May to July.

This species seems to have undergone a significant 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 45% over a ten year period.

Destruction of heathland and grassland for building and agricultural development. Drainage of wet areas in these habitats.

Management and conservation
Prevent further habitat loss in heathlands and grasslands due to urban and agricultural development. Maintain wet areas in heathlands and grasslands.
