Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

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.

Yellow Horned Achlya flavicornis

(Linnaeus, 1758)


Wingspan 35-40 mm.

The English and scientific names of this moth are derived from the yellowish colour of the antennae.

The adult is greyish, with a finely speckled appearance, and has darker cross-lines and a distinct whitish spot.

It is an early species, flying in March and April, and inhabits woodland and heaths where birch (Betula), the larval foodplant, occurs.

It is generally distributed and fairly common in Britain; in Scotland, the larger and darker scotica race occurs.
