Wingspan 24-28 mm. This is one of the most familiar of the Pyralidae, with its yellowish body parts and black-and-white patterned wings.

Any habitat where Nettles are found.

Flies in June and July.

The main food plant is Nettle, but Woundworts, Mints, Horehounds and Bindweeds are also used. The larva feeds from a rolled or spun leaf in August and September before hibernating in a tough silk cocoon in a hollow stem or under bark. Pupation occurs in May in the same cocoon, without further feeding.

It is very common in the Southern half of Britain, becoming less so further North. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.

Common in Leicestershire and Rutland. L&R Moth Group status = A (common and resident)
