The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Formerly widely recorded across southern Britain, but recently reported from only three vice-counties.
Reported from Perranporth Dunes (Tomlin, 1909), and from gull nests on Annet (Joy,
1909; Mackechnie-Jarvis, 1966). W.W. Fowler is credited with the first discovery of the
species on the Isles of Scilly before 1887 (Blair, 1931).
Habitat & Ecology
Known from a variety of situations, most usually in damp places amongst moss and plant litter, but also in ant nests, and nests of cormorants and gulls.
Loss of semi-natural rough pastures; agricultural intensification.
Protection of semi-natural pastures from inappropriate developments.
