– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: Very similar to the un-banded form of Riband Wave (remutata). Slightly smaller with smooth silky grey-brown coloured wings and fainter cross-lines. The third cross-line is missing the kink of Riband Wave.
Distribution: (First record: 1951 ) – (Last record: 22 July 2025 at Longdendale ) – A species that seems to be very scarce and locally distributed in Derbyshire, mainly in the central NW. It maybe overlooked amongst Riband Wave Idea remutata. Usually only single specimens trapped most years. Added to the county list in 1951.
