For the county, we have a total of 300 records from 256 sites. First recorded in 1994.
Most records are of leaf-mines.
Sutton & Beaumont, 1989: Shown as occurring in vice-counties 61, 62 and 65 on map 34 in MBGBI 1.
Argus 56, 2008: This moth is widespread throughout the county, however it was overlooked that there is no published VC64 record, accordingly the first known record is listed below together with localities within the vice-county from where it was recorded during 2008, although there have been further records in the intervening years. All records refer to larval mines on Oak.

2013 (CHF):Leaf mines on oak are extremely common all over the county. The egg is laid on the upperside of the leaf, next to a vein. The first part of the mine is a narrow corridor, with a broad frass line, running along a vein. Usually the corridor runs away from the midrib, but often it runs along the midrib itself. The corridor widens abruptly into a squarish blotch, containing much frass. There are often several mines in one leaf. The two confusion species are the late-mining Ectoedemia subbimaculella where the larva makes a conspicuous slit in the lower epidermis of the blotch, by which part of the frass is ejected, and the much less common Ectoedemia heringi where the early gallery tender to run towards the midrib rather than away, and the larva has a red-brown head rather than the pale brown of albifasciella.
