For the county, we have a total of 22 records from 21 sites. First recorded in 1883.
Most records are of leaf-mines.
Sutton & Beaumont, 1989: A local moth with scattered records from vice-counties 62, 63 and 64.
Argus 50, 2005:
VC65. High Batts NR., mine on alder 19.8.2005 (CHF). NEW VICE-COUNTY RECORD.
2013 (CHF): Locally common on alder. We have no records from VC61. Adults can be seen flying round alder branches in early summer though most of our records are of the characteristic leaf mines in the autumn. The mine begins in a major vein then the larva descends to the midrib. To do this it often moves from one thick vein to another my means of a slender corridor. It then descends into the petiole before returning up the midrib and making a short corridor leading to an oval excision 2 x 5mm in which the larva drops to the ground.
