Resident. Often occurs sparingly or fairly commonly in deciduous woods and on wooded heaths. Probably generally distributed in the far east and far west, and in the north, but colonies are scarce elsewhere. Any real numbers are very local throughout. In decline, and disappearing from central Sussex. Single-brooded, flying mainly from late May or to late August. Specimens occasionally occur in September and October. Larvae feed on birch.
