Wingspan c.14 mm.
One of the more easily identifiable Coleophorids as an adult, having whitish forewings speckled with dark grey and usually an obvious blackish spot at around three-quarters.
The species spends two years as a larva, the first one-and-a-half years in a small pistol-case, and in the second spring building a long straight case which is dark brown and rather distinctive. The larva feeds on hawthorn (Crataegus), apple (Malus) and a number of other Rosaceae.
It occurs locally in the south east of England, and the adults fly during July.
