Wingspan 9-10 mm.
Although this moth is found widely throughout Britain, it tends to be found locally and even then is seldom common.
The larval foodplants are honeysuckle (Lonicera>), snowberry (Symphoricarpos) and occasionally flowering nutmeg (Leycesteria).
The moth is bivoltine, being in flight in May and August. The underside mines formed are large and cause the leaf to become creased. Mines are found in July and again in September and October.
