Common Green Darner

<em>Anax junius</em>, commonly known as the common green darner, is a large dragonfly belonging to the genus Anax within the family Aeshnidae. This species occupies virtually all terrestrial and freshwater habitats, and its range is centered on the United States, where it is one of the most recognizable and widespread dragonfly species. Common green darner is assessed as Least Concern on the IUCN Red List. The species is well known for undertaking long-distance migrations, with populations moving southward in autumn and northward in spring across North America. Adults are typically found near ponds, lakes, and slow-moving streams where females deposit eggs in aquatic vegetation. Biological traits of this species remain poorly documented in the scientific literature.

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.
