Makelrand-Grasbüscheleule

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.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
