Species Account


Most records are of leaf-mines.

Sutton & Beaumont, 1989: Records are thinly distributed throughout vice-counties 61 to 64, not recorded from VC65.

2013 (CHF): This species is rather local in the county with leaf mines on apple, both wild and cultivated. Mines are very variable. The gallery is a tortuous corridor, and sometimes only widens a little but at other times ends in a false blotch. The frass is black or brown, in a narrow central line and these features should separate the species from Ectoedemia atricollis or Stigmella oxyacanthella. The other confusion species could be Stigmella desperatella though this has not (yet!) been found in the county. Typical tenanted mines with their yellow larva however should not produce a problem.
