Crescent Striped Apamea oblonga
Wingspan 42-50 mm.
Mainly a species of salt-marshes, estuaries and similar coastal habitats, this moth occurs along the south and east coasts sporadically from the Isle of Wight to Humberside, and in a few scattered locations in the west.
The moths are on the wing from June until August, and can be attracted to light.
The larval foodplant is mainly saltmarsh-grass (Puccinellia spp.), especially the bases of the stems and roots.
