Gesellige Sandbiene

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.

Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
