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
Previously misidentified as I. albicomella , which is thought to no longer occur in Cornwall ( I. albicomella is found in four other localities in the British Isles) (Heckford, 2005). I. captans has not previously been recorded in the British Isles and certainly warrants RDB status. Found in Europe from France, Switzerland, Italy, Austria and Yugoslavia.
Recorded in six separate areas in west Cornwall (VC1), five on the north coast and one on the west coast of the Lizard Peninsula.
Habitat & Ecology
The larvae feed on the ground in silken spinnings amongst black frass, detritus and dead leaves of Hairy Green-weed Genista pilosa and the dead leaves and dead flowers of Bell Heather Erica cinerea , especially where the vegetation was sparse.
