History
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 with it still remaining the chief site for this local moth.
 
Gordon (1913) under A. philanthiformis states two were taken by Hugh McDowall on cliffs at Portpatrick in 1886.
 
From 1995 to 2005 we have a further twenty records, all at coastal localities, but none from Dumfriesshire. The next two came in 2012 from Wigtownshire, with a further three records during 2013, one in VC74 with the other two from VC73.
 
Life cycle
One generation. Overwinters as a part-grown larva during August to May, feeding in the roots and stems of Thrift.
 
A middle of the day moth flying species that is easily overlooked as being a fly or a bee, visiting flowers of Thrift and Thyme. Males can be attracted by pheromone lures.
 
Larval foodplants
Thrift.
 
Identification
The smallest Clearwing which has three or four narrow yellowish-white bands on the abdomen. The wings are transparent with black veins.
