Eratophyes amasiella
This beautiful moth has a wingspan of 12 to 16 mm only. In Europe there is no species like it, so it is very easy to put a name on. It was probably introduced in the Netherlands in the 20th century and has since conquered Germany, Sweden, Belgium and Denmark. It's original home is Minor Asia, especially Turkey. The larvae live in decaying wood, especially that of birch and willow. It is on the wing in May and June.
Eratophyes amasiella has not been recorded on the British Isles yet. Given the way it is expanding from the Netherlands however, it may appear in Britain one day.
