Sutton & Beaumont, 1989: Widely recorded from all five vice-counties. Porritt (1907) gave its status as common but there are relatively few recent records.
2013 (CHF): An uncommon moth in the county where it can be found on heathland and open woodland with birches. The tiny adults come to light but the moth is more often encountered as a leaf mine. The initial corridor is long and very narrow, winding through the leaf and often crossing the midrib. This then abruptly widens into an irregular elongated blotch. At the end of the blotch the larva makes an oval excision about 4mm in diameter in which it drops to the ground for pupation. Mines are usually found in the youngest leaves.
