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.

Bacotia claustrella

(Bruand, 1845)

[Synonyms: Bacotia sepium]
Wingspan (male) c.14 mm.

A scarce species in Britain, occurring only in certain southern English counties.

As with many other Psychids, the females are apterous, and have reduced legs. The males are fully winged and rather dull brown in appearance.

The larva builds a case covered with lichen and fragments of bark, and rests with the case projecting at right angles from the bark, resembling a bud or stunted side shoot.

The normal emergence period for the adults is June and July, and the larvae feed from autumn, overwintering and feeding again in the spring up until about May.
