Larval foodplants



Rocky coastlines where Thrift is present.


Robinson-Douglas (1870-71) had found the larvae abundant on Thrift along the coast in July. He also recorded finding an injured pupa. Francis Buchanan White of Perth (1895) found it not uncommon on the rocky coast where Thrift grows. He noted Colvend (VC73) as the first Scottish locality, it still remaining the chief site for this local moth.

Gordon (1913) under A. philanthiformis stated that two were taken by Hugh McDowall on cliffs at Portpatrick in 1886.

From 1995 to 2005 there were a further twenty records, all at coastal localities, but none from Dumfriesshire.
