clouded brindle

The clouded brindle (Apamea epomidion) is a noctuid moth in the family Noctuidae found across temperate Europe and extending into western Asia. The adult wingspan measures approximately 35–45 mm with typical brindle-patterned forewings in grey-brown and buff tones with subtle cross-lines and stigmata characteristic of the Apamea genus. The term 'clouded' refers to diffuse cloud-like darker shading areas across the forewing surface. Adults fly in one generation from June to August, attracted to light and flowers at night. The larvae are internal feeders within grass stems and roots, feeding on coarse grass species such as Brachypodium sylvaticum and Deschampsia in woodland rides, scrub margins, and rough grassland habitats. The pupal stage overwinters in soil or within plant debris. The clouded brindle inhabits structurally diverse woodland edge habitats with a mixture of tall grasses, scrub, and open canopy woodland rides that provide both larval foodplants and adult resting sites. Changes in woodland management, particularly reduction of coppicing and shading of woodland rides, may affect this and related grass-feeding brindle moth species.
