As soon as a replacement map service is available, distribution maps will hopefully appear here again.
In the meantime, you can get some idea of distribution from the NBN Atlas website.

Acleris emargana
(Fabricius, 1775)
Wingspan 18-22 mm.
The notched and hooked forewings of this species create a very distinctive outline, but the depth of the emargination varies, and can even be absent.
The species has recently been split from 1062a E. effractana, which is more of a northern species. For differences, see that species.
The larvae feed on the leaves and shoots of trees such as sallow (Salix), poplar (Populus) and birch (Betula).
Flying from July to September, the species is commonest in the south of Britain, becoming less common further north.
