Common Spruce Bell

Epinotia tedella, commonly known as the common spruce bell, is a small tortrix moth in the family Tortricidae, distributed across Europe wherever its primary host plant, Picea abies (Norway spruce), occurs. This species typically inhabits spruce forests, forest plantations, and woodland edges with significant spruce components, from lowland areas to montane elevations throughout much of the European continent. Its geographic range extends from Scandinavia and the British Isles south through central and eastern Europe, broadly following the distribution of its conifer hosts. Classified as Least Concern on the IUCN Red List, Epinotia tedella maintains stable populations across its range and is not considered threatened. The larvae feed internally within the needles of Picea species, mining leaf tissue and occasionally causing noticeable damage during outbreak years in plantation forestry. Adults are small moths with a wingspan of approximately 12–16 mm, displaying forewing patterns of brownish-grey with silvery strigulae typical of the genus. The species produces one generation per year, with adults flying from late spring to midsummer. Biological traits such as average lifespan in years, precise body weight, and detailed population dynamics remain poorly documented for this minor forestry pest. Diet consists primarily of Norway spruce needle tissue during the larval stage.

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。
