clifden nonpareil

The Clifden Nonpareil, Catocala fraxini, is one of Europe's largest and most spectacular moths in the family Erebidae, named for the village of Clifden in Ireland where early specimens were recorded, with 'nonpareil' meaning 'without equal' in French. The forewings are subtly beautiful, with complex gray, brown, and black marbling that provides excellent camouflage against bark when at rest. When disturbed, the moth reveals startlingly vivid hindwings marked with broad bands of blue-lilac and black, a classic startle display intended to deter predators. Adults have a wingspan of up to 90 mm. The species is found from western Europe east through central Asia to Japan, inhabiting mature deciduous woodland and riverside forests where aspen (Populus tremula) and poplars (Populus species) grow, as these are the larval food plants. Adults fly in late summer and autumn, visiting blackberry, ivy, and overripe fruit for sugar-rich food. The Clifden Nonpareil was once widespread in Britain but underwent severe decline during the 20th century due to loss of mature poplar woodland and riverside habitat. Conservation efforts including habitat restoration have allowed gradual recolonization of former British sites. The species is now slowly recovering in parts of southern England.

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。
