Range & Status
Very localised in southern Britain and has become increasingly scarce.
Joy (1908) refers to a record from the Isles of Scilly in April 1908, when it was found ' not rare by shaking old bundles of reeds lying on the ground' and indicates that he also found it on the neighbouring mainland on the same trip. The record is given as Tresco in the national Carabidae Recording Scheme dataset.
Habitat & Ecology
Found on mud or in lush vegetation of Reedmace Typha spp., sedges Carex spp. and Common Reed Phragmites australis .
