ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Clubbed General

Stratiomys chamaeleon is a soldier fly in the family Stratiomyidae, commonly known as the clubbed general. It is a large, distinctive fly with wasp-like yellow and black banding on the abdomen, giving it an aposematic appearance. Adults are frequently observed visiting flowers for nectar and pollen in wet meadows, marshes, and fens, particularly in western and northern Europe. The species is associated with wetland habitats, where larvae develop aquatically or semi-aquatically in waterlogged soils, mud, decaying organic matter near water margins, and occasionally in dung. Larvae are elongated, flat-bodied, and breathe via a respiratory siphon at the tail end. Adults are strong fliers capable of covering considerable distances between habitat patches. Stratiomys chamaeleon is considered Near Threatened, reflecting the significant loss and degradation of wet grassland and fen habitats across Europe due to drainage for agriculture, peat extraction, and development. The species requires mosaics of open water, wet soil, and flowering plants to complete its life cycle. Conservation depends on wetland restoration and maintenance of traditional wet meadow management.
