– click for Adult Macro Verification Guidelines
– Rare / Uncommon / Scarce
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: The most likely confusion species are Common Wainscot and Smoky Wainscot.
ID pointers: The outer edge (Termen) of the forewing is much straighter than related species and there is a noticeable outward projection at the wing tip (Apical point) and a row of black post-median dots on the forewing can help to identify. Ground colour is a soft light greyish straw, sometimes tinged with a pinkish-brown. A brown streak runs along the central vein.
Hindwing is whitish to pale greyish with a dark discal mark and a row of short dark postmedian dashes. Another identification aid is the white and brown double striped collar, giving the illusion the moth is wearing a headband, if viewed from the front.

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.
