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.

Scarce in Britain and Ireland, and largely absent from Scotland except its extreme southwest coast.
First recorded on the Isles of Scilly in 1985, and more specifically Gugh, Bryher, Tresco and Tean in 1986 and 1987. The only mainland record is for the Land' s End area in 1998.

The Isles of Scilly are designated for nature conservation.
