Clouded Cavalier

Clouded cavalier refers to a moth or butterfly species bearing the 'cavalier' designation, likely referring to a hesperiid skipper or noctuid moth with distinctive clouded, mottled patterning on the wings. Cavalier-named lepidopteran species typically occur in tropical or subtropical regions, and the clouded form may be found in South or Southeast Asian forests or savanna habitats. Members of this type often display neutral brown, grey, and white wing patterning that provides camouflage against bark, soil, or leaf litter substrates on which they rest during the day. Larval foodplants in these groups typically include grasses, sedges, or herbaceous plants appropriate to the family of the species concerned. Many 'cavalier' skippers and related hesperiids inhabit forest margins, clearings, and disturbed habitats where sunlight penetrates the canopy, providing warm basking spots and nectar sources for adults. Documentation of species like the clouded cavalier contributes to understanding the remarkable diversity of tropical and subtropical Lepidoptera in regions experiencing ongoing habitat pressures from forest clearance and land conversion.

Eurasian beaver

ユーラシアビーバー（Castor fiber）はIUCNレッドリストで絶滅危惧II類（VU）に分類されています。個体群の減少と生息地への圧力の増大により、野生での絶滅危険度が高い状況に直面しています。
