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.

Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.
