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 very widespread in coastal Britain but very localised. The few modern records are all from the south-west, including Cornwall.
Reported from Porthcurno and Grochall, Lizard by M.G. Morris in 1974; also the track
from Chyvarloe to Loe Bar and at Ruan Lanihorne by A.P. Foster in 1980 and 1995
respectively. Subsequent records suggest that it is fairly widespread in the west and
readily to be found.
Habitat & Ecology
Associated with Blackthorn Prunus spinosa , larvae almost certainly in the flowerbuds.
Penrose Estate is National Trust property.
