PDF Icon – click for General Verification Guidelines  |   PDF Icon – click for Specific Verification Guidelines
Green –  Rare / Uncommon / Scarce        day-flying – Day-flying
Taxonomy:   Micro   >>  Tortricidae  >> Tortricinae
Other Name/s: Heather Twist
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
ID pointers: Quite distinctive. Panels of dark brown and pale cream across the closed forewing. A rusty brown scale tuft in the basal area of the forewing. 
Distribution:  (Last record: 12 April 2025 at Hollingworth Clough )  –  Despite being a moorland species and with very few records since 1988. Of the 25 records received all are from three locations in the south east corner of the county – Sandiacre, Breaston and Long Eaton. One record from Belper. A record from the north Derbyshire moors 12/4/2025 from Hollingworth Clough. I’m sure this species is under-recorded on the heather moors of the recording area.

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.
