Classification
| Family: | Nepticulidae |
| Subfamily: | Nepticulinae |
| Genus: | Stigmella |
| Species: | poterii |
| Authority: | (Stainton, 1857) |
Nationally scarce (Nb) on chalk and limestone districts throughout much of south-eastern England, and in Cumbria and Lancashire. in Hampshire recorded only from a narrow band between Leckford and St Catherine's Hill, and at Noar Hill and Emer Bog; on the Isle of Wight, recorded in recent years just once, at Tennyson Down. Wingspan 3.5-5 mm. Adults difficult to distinguish from other Stigmella species, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Salad Burnet, over-wintering as a pupa. In Scotland, f. tengstroemi occurs on damp moorland, where the larva mines Cloudberry and Stone Bramble. Throughout the species' range, f. serella, the larva of which mines Tormentil and which was previously afforded specific status, occurs.
