Cornish Red Data (2009)

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.

Homoeosoma nimbella

Range & Status

The exact status of this species in Britain is difficult to determine because of its similarity to the commoner coastal species Phycitodes saxicola (Vaughan); the separation of these two species was not published until 1937 (Pierce, 1937). The only confirmed post-1970 British records are from Cornwall (Parsons, 1993), in 1993 from the Isles of Scilly, in Norfolk in 1993, and in 1994 (B.F. Skinner, pers. comm.) and from Dorset. This species is widespread on the Continent.

Regional Distribution

Recorded at Lamorna in 1979 (Agassiz, Heckford & Langmaid, 1992); there are previous records from Redruth. This species might be common but overlooked in Cornwall in suitable coastal habitat. Also recorded on St. Mary' s in 1993 (Heckford, 1994b).

Habitat & Ecology

The larvae feed on Sheep' s-bit Jasione montana (Heckford, 1998).


None known.
