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.

Cosmopterix orichalcea

Stainton, 1861


Wingspan c. 9mm

Occupying damp habitats such as fens and river banks, this species is to be found locally in a number of localities ranging from southern England to Wales, as well as parts of Ireland and the Western Isles in Scotland.

It is similar in appearance to other Cosmopterix species, but has a much more distinct large metallic patch at the base of the forewing.

The larvae feed on a number of grasses (Poaceae), mining the blades and forming an irregular gallery.

Adult moths occur from late May to August.
