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.

Pseudoswammerdamia combinella

(Hübner, 1786)

Wingspan 13-16 mm.

Distributed sparsely throughout most of Britain, this is one of the larger species in its group, with a wingspan of up to 16mm.

The dark-bordered orange spot at the end of the forewing is diagnostic.

Flying in May and June, the adults are sometimes attracted to light. Blackthorn (Prunus spinosa) is the foodplant, the small larvae leaf-mining at first, and later living externaly in a silken web.
