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.

compact rustwort

<em>Marsupella condensata</em>, the compact rustwort, is a small leafy liverwort in the family Gymnomitriaceae found in Arctic and alpine habitats in Europe, with documented occurrences in Norway and Sweden. Liverworts in the genus Marsupella are characterised by their simple thalloid or leafy structure and specialisation for cold, wet, and exposed environments including snowflush communities, fellfields, and soliflucted soils at high elevation or high latitude. Compact rustwort typically grows in moist, acidic substrates near late-lying snow patches and on wet rock surfaces in montane tundra and alpine heath. These habitats are highly sensitive to climate change, with warming temperatures and reduced snowpack directly threatening snowflush plant communities across Scandinavia. The IUCN classifies <em>Marsupella condensata</em> as Least Concern, although its dependence on cold, moist microhabitats makes it potentially sensitive to long-term climate warming. The species contributes to biological soil crusts and serves as a substrate for invertebrates and microorganisms in fragile alpine ecosystems. Bryophytes like compact rustwort are often slow-growing and slow to recolonise following disturbance. Biological traits including growth rates, reproductive biology, and precise morphological measurements remain poorly documented, as is typical for many liverwort species outside specialist botanical surveys. Its conservation depends on the preservation of intact alpine and Arctic habitats across Scandinavia.
