** This page is to record aggregated records only – see individual species pages for additional information. **
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species: Dark-barred Twin-spot Carpet – Xanthorhoe ferrugata; Red Twin-sport Carpet – Xanthorhoe spadicearia
ID pointers: For many years, it was thought the way to separate Dark-barred Twin-spot Carpet from Red Twin-spot Carpet was to look for a distinct ‘notch’ in the whitish line on the inner edge of the dark central band. However, this has recently been proven to be unreliable as a determining factor. Red Twin-spot Carpet tends to have more distinct whitish bands either side of the central dark band, but the different forms of both species make this a difficult pair to separate visually. For further details see the separate species pages
Distribution:  Both species are uncommon across the recording area – See separate species pages for further details

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.
