Common Green Capsid

<em>Lygocoris pabulinus</em>, commonly known as the common green capsid, is a plant bug belonging to the genus Lygocoris within the family Miridae. The species inhabits virtually all terrestrial and freshwater habitats, reflecting a generalist ecological strategy. Its documented range spans Taiwan in Asia, four European countries, and both Canada and the United States in North America. Common green capsid is assessed as Least Concern on the IUCN Red List. This small heteropteran is typically bright green in color and is associated with a wide variety of herbaceous and woody host plants, occasionally reaching pest status in agricultural settings where it damages soft plant tissue. 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.
