Wingspan 11-13 mm.
A distinctive 'pied' appearance makes this Gelechiid one of the less difficult to identify. It is distributed in central and southern England, and occurs in continental Europe.
The larval stages are yet to be fully described in this country although on the continent it is believed to be associated with oak (Quercus) as well as mosses on tree-trunks.
The moths fly in May and June and are attracted to light.
