Range & Status
Largely a Mediterranean species, and only known in Britain from the north coast of
Cornwall. Difficult to find due to extreme localisation of small colonies within areas of the foodplant, so possibly under-recorded.
There are only three records for Cornwall: Rock, near Padstow (in 1956 and 1957) and at Porth Kidney Sands, near St. Ives (in 1968). Recent searches at Rock have failed to re-find the species.
Habitat & Ecology
It lives in very localised colonies on Lady' s Bedstraw Galium verum on sand dunes. The nymphs form extensive feeding damage to the leaves, in the form of large white patches.
The 1956 colony is reported to have been destroyed by a wind-blow. Natural processes of erosion and deposition within the dune system are therefore a problem although one which the species has lived with for generations. Public access may exacerbate the problem. Development pressure, particularly holiday camps, camping and caravan sites, etc. can be a threat. Abandonment of coastal grazing also leads to habitat loss.
