Chocolate Mining Bee

The Chocolate Mining Bee (Andrena carantonica) is a medium-sized solitary bee in the family Andrenidae, native to Europe and extending across temperate Eurasia. Mining bees of the genus Andrena are ground-nesting bees that excavate burrows in soft or sandy soils, creating underground cells provisioned with pollen and nectar as larval food. Andrena carantonica is one of several spring-emerging Andrena species associated with fruit trees and spring-flowering plants; females frequently visit the flowers of apple, cherry, hawthorn, willow, and other early-season species, making them important pollinators of both wild plants and orchard crops. The species is often an early-season visitor alongside other spring bees, making it an important pollination service provider before managed honeybee colonies are at full strength. Males typically emerge before females, patrolling host plant patches in search of mates. The species is eusocial in the broad sense, with females sometimes nesting in loose aggregations in favoured soil sites. The IUCN classifies Andrena carantonica as Least Concern; it is one of the more widespread and frequently recorded Andrena species across its range. Threats to mining bee populations generally include loss of nesting habitat (bare ground), loss of floral resources through agricultural intensification, and pesticide use.

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.
