Wingspan 15 to 19 mm (male). The females are completely wingless, resembling small yellow grubs. The males are dull brownish affairs.
Usually found by locating the case on trees or fences with a covering of lichen.
The adult moths appear in May and June.
Members of this family are sometimes known as 'bagworms' because of the larval habit of constructing a case, or bag, in which to live. This species produces a long, narrow case made from fragments of sand, lichen and bark, bound together with silk, and the larva feeds on lichens where the case is attached (usually a tree trunk or fence).
Sparsely scattered through central and southern England and Wales. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
