Habitat & Geographic Range

Common Least Skipper

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Canada and United States.

爪哇禾雀

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 6 distinct biome types spanning the Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Tanzania), Asia (Taiwan, Thailand, Vietnam), Europe (5 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Colombia, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

爪哇禾雀

爪哇禾雀是东亚最受欢迎的笼鸟之一，外形优美，具有灰色羽毛、醒目的黑色头部、白色颊斑和鲜红色喙。原产于印度尼西亚的爪哇岛和巴厘岛，已被引入亚洲、非洲和美洲的许多地区。栖息于开阔草地、水稻田和农耕地，有时会危害水稻作物。由于笼鸟贸易的严重捕捉压力，在原产地被列为易危物种。
