| Genus: | Heliozela |
| Species: | hammoniella |
| Authority: | Sorhagen, 1885 |
Local on heathland, scrubland and fens in Britain as far north as the Lake District. In Hampshire and on the Isle of Wight restricted to a handful of sites, mainly in the south of the county, notably Botley Wood and Emer Bog, and very rare in the north and on the Island. Wingspan 5-7 mm. Adults are day-flying, and the species is more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines twigs and leaves of Birch, over-wintering as a pupa. The mines are described in the following link:
