clouded-bordered brindle

The clouded bordered brindle (Apamea crenata) is a noctuid moth in the family Noctuidae found across temperate Europe and across northern Asia to Japan. The adult wingspan measures approximately 38–45 mm, with intricately patterned grey-brown and buff forewings bearing subtle cross-lines, a scalloped (crenate) outer margin giving the species its name, and distinctive reniform and orbicular markings characteristic of the Apamea genus. Adults fly in one generation from May to July, visiting flowers for nectar at night. The larvae feed internally within the stems and roots of grasses, particularly Brachypodium and other coarse grass species in woodland rides, woodland margins, and rough grassland habitats. Overwintering occurs as a larva within plant stems. Like many grass-feeding noctuids, the clouded bordered brindle requires structural diversity in its grassland and woodland edge habitats, with areas of tall, tussocky grasses providing both larval foodplants and adult shelter. Population trends in parts of its European range reflect changes in land management affecting coarse grassland and woodland ride quality.
