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.

Argyresthia semitestacella

(Curtis, 1833)

Wingspan c.11-14mm.

This species is distributed fairly widely over much of the British Isles, and is one of the larger of the Argyresthia species. It has a relatively plain golden brown forewing with a whitish dorsal streak extending for much of the forewing length.

It is quite a late flyer, being on the wing in August and September.

The larva feeds on the shoots of beech (Fagus), and can be found in May and June.
