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
Confined in Britain to Cornwall, where it was recorded in 1991 (Heckford, 1994a); this species has also been recorded from France, Spain, Portugal, Sardinia, Sicily, Malta, Italy, Greece and Crete (Karsholt & Razowski, 1996).
Originally considered to be resident in Cornwall but listed in Bradley (1998) as a suspected adventive and now thought to have been transported to Cornwall by strong southerly winds (Koster & Sinev, 2003).
Habitat & Ecology
It is thought that the larvae feed on the waxy secretions of Homopteran bugs which in turn feed on plants, possibly the Common Reed Phragmites australis .
