Classification
| Family: | Nepticulidae |
| Subfamily: | Nepticulinae |
| Genus: | Stigmella |
| Species: | malella |
| Authority: | (Stainton, 1854) |
Local throughout much of England, rare elsewhere in Britain. Probably under-recorded in Hampshire and on the Isle of Wight, where the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 4.5-5.5 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 Apple, causing sufficient damage to be a serious pest in some areas, over-wintering as a pupa. The mines are described in the following link:
