Épithèque à Queue de Beagle

The common baskettail (<em>Epitheca cynosura</em>) is a dragonfly found across terrestrial and freshwater habitats of the United States. It is classified as Least Concern on the IUCN Red List, reflecting a stable and widespread population within its native range. <em>Epitheca cynosura</em> belongs to the family Corduliidae and is typically associated with ponds, lakes, marshes, and slow-moving streams, where its aquatic larvae develop. Adults are often observed patrolling over open water and forest edges in search of prey and mates. The species is named for the basket-like egg mass that females carry at the tip of their abdomen before depositing eggs in water. Males often form feeding swarms, particularly in the morning hours, where they capture small flying insects. 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.
