アスペロコッカス・エンシフォルミス（Asperococcus ensiformis）は北大西洋・地中海沿岸の岩礁基質に付着する管状〜扁平な茶藻類で、細長い袋状〜剣形の葉状体を形成する。潮間帯から浅い潮下帯の波浪暴露域の岩石・大型藻類に着生する光合成植物である。コンブ目に近縁な褐藻類として、沿岸生態系の一次生産者として機能している。

Common Least Skipper

The Common Least Skipper (<em>Ancyloxypha numitor</em>) is a small butterfly in the family Hesperiidae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically inhabits virtually all terrestrial and freshwater habitats within its range, showing a particular affinity for moist, grassy areas near water. The species is among the smallest skippers in North America, characterized by orange and brown wing coloration and a rapid, low-flying flight pattern close to vegetation. Adults typically nectar on small flowers while larvae feed on grasses, particularly those in wet meadows, marshes, stream margins, and disturbed grassy areas. The Common Least Skipper is frequently observed in wetland margins, wet prairies, and roadsides with rank grass growth. Its wide distribution across North America and habitat generalism across moist grassland and wetland types support its stable population and Least Concern conservation status. Biological traits of this species remain poorly documented in the scientific literature.
