Elachista biatomella: Distribution map

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.

Elachista biatomella

(Stainton, 1848)


Wingspan c.8mm.

Apart from the two elongated black spots, this species can also show some darker speckling, though this is more pronounced in the male than the female.

It has a fairly wide but scattered distribution across much of England and Wales, occupying grassy habitats and heaths.

The larvae feed on sedge, notably glaucous sedge (Carex flacca), forming a whitish elongated mine containing frass.

There are two generations, with adults in May-June and in July-August.
