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.

Ochrolechia subviridis는 해양성 및 산악 서식지의 규산질 암석과 나무 껍질에 두꺼운 녹회색에서 흰색 반점을 형성하는 각피성 지의류다. 창백하고 분말 상태의 표면을 가진 원판 모양의 자실층을 생성하며, 우스닌산 화합물을 함유한다. 취약 상태는 제한된 서식 범위 내에서 서식지 변화와 대기 오염에 대한 민감성을 반영한다.
