Species Account

Most records are of leaf-mines.

Sutton & Beaumont, 1989: Sparsely recorded with scattered records from vice-counties 61, 63 and 65.

2013 (CHF): There are several Stigmella species which mine on birch and identification is not always straightforward so care should be taken. This is a rare species in the county or perhaps just under-recorded. The egg is on the underneath of the leaf close to a vein. The mine is a short tortuous corridor. The first part does not encircle the egg. The mine edges are parallel and smooth unlike the "scalloped out" edges of luteella, the main confusion species. There are usually several mines in a leaf. The larva is bright yellow with a green gut line, a line of dark ventral spots and a small brown spot on the prothorax. Mines are commonest on low scrub and seedlings.
