STATUS – A scarce immigrant to Derbyshire. During 2006 an unprecedented number of Scarce Bordered Straw moths arrived in Britain. During this invasion the species was added to the Derbyshire List as a genuine vagrant. The following images were from specimens trapped in my garden. In 2017 two individuals were recorded and a further specimen from Buxton in 2018. A specimen trapped 28th July 2022 at a time of numerous migrant moths in the UK. One trapped at Chaddesden, Derby during September 2023 by Martin Roome.

Forewing has a darker brown cross-band near the outer edge and a dark cross-line through the middle of the wing. Some individuals show hardly any obvious markings. Kidney & oval marks have a dark central spot.
