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.
