Common Yellow-face Bee

Hylaeus communis, the common yellow-face bee, is a small solitary bee in the family Colletidae. It is widely distributed across much of Europe and western Asia, where it is one of the most frequently encountered members of its genus. The species inhabits a broad range of open and semi-open habitats including gardens, meadows, hedgerows, heathlands, and woodland edges, often nesting in existing cavities such as hollow plant stems, galls, and old beetle burrows. Adults are small, typically 6–8 mm in length, and are characterized by yellow facial markings on an otherwise black body, the pattern being more extensive in males than females. Biological traits such as average lifespan, precise body weight, and detailed population estimates remain poorly documented in the scientific literature. Unlike many bees, Hylaeus species lack specialized pollen-carrying structures; instead, they transport pollen and nectar internally in their crop. Adults visit a wide variety of flowers for food and are considered polylectic generalists. Hylaeus communis is assessed as Least Concern, reflecting its broad distribution and tolerance of diverse habitats, though it may be affected by loss of nesting sites and floral diversity in intensively managed landscapes.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
