ID pointers: The forewing is brown or a dull grey-brown with an obvious contrasting brown cross-band that is wavy and jagged on the outer edge and that is finely bordered with a chalky white edging. there are two blackish spots near the pointed wing tip. The cross-band appears “pinched in” towards the trailing edge of the forewing.

First 2 records – 1980 & 1981 – Shardlow/Long Eaton. Then three records from two sites near Ripley in 2012,2013 & 2016 would indicate a small localised colony.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
