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
Only recently recognised as a British species, and known from a number of sites on
the coasts of Pembrokeshire, north Wales and Cornwall. Essentially Mediterranean in distribution, but also extending along the Atlantic coasts to north-west France.
Only known from The Lizard area at present. Bannister collected a pair of this species from Wild Thyme Thymus polytrichus at Loe Bar in 1964. Also found on Beagles Point on The Lizard in 1989 (Alexander, unpublished).
Habitat & Ecology
Larval foodplant is Wild Thyme and all the known localities are rocky coastal situations.
Loss of rough cliff grazings, leading to coarsening and scrub development.
The known sites are owned by The National Trust.
