Mathew's Wainscot Mythimna favicolor
Wingspan c. 35-40mm.
Considered by some authorities to be a saltmarsh race of Common Wainscot (M. pallens), it does presently however have specific status in most literature.
A scarce species, occurring in saltmarsh habitats in the south-eastern coastal counties of England, where it flies in June and July.
The larva feeds on common saltmarsh-grass (Puccinellia maritima) and maybe also other grasses.
