About this speciesRecorded altitude range
30m to 674m
The few records are widely scattered, but with very few recent captures. The species is widespread in north-western and central Europe, but it has not been recorded from Ireland.
Habitat and ecology
Woodland and scrub. The spider occurs on low plants among scrub and overgrown woodland, and on young oaks. A male appeared in a Robinson light trap set for moths in scrub in West Lancashire in May. Adults of both sexes are found in September and May. It possibly over-winters as an adult.
Recorded from only five hectads since 1992, showing a decline of more than 50% in hectads with spider records both before and after that date (11 to 5). Although clearly very local, its wide distribution suggests that it may have been overlooked in some places, perhaps because it matures late in the season or perhaps it occupies a slightly unusual habitat.
The clearance of scrub and old woodland for intensive forestry, and the removal of shrub layer vegetation.
Management and conservation
Maintain low plants and shrub layer in old woodland.
