The moths are on the wing in late May and June, and fly during the day in sunshine, visiting flowers.

The larvae are thought to feed at first on flowers of sea-buckthorn or privet, later building a portable case from leaf fragments and particles of soil and feeding on leaves which have fallen.

Distributed locally throughout England and Wales. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
