Argus 47, 2004:
VC63. Potteric Car NR, mines on oak 2003, reared 7.5.2004 (RIH). NEW VICE-COUNTY RECORD.

2013 (CHF):This species is probably more common than the records suggest. Mines are easily confused with Ectoedemia albifasciella but the larvae has a dark brown head compared to the pale brown of albifasciella. The egg is laid on the upperside of the leaf, next to a vein. The mine begins as a narrow corridor with a broad frass line, running along a vein. Generally the corridor runs along the midrib, or along a lateral vein. In the latter case the direction usually is towards the midrib. The corridor abruptly widens into a blotch, containing much frass, laying against the midrib.
