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.

Streaked Saltator

A medium-sized saltator of Pacific coastal lowlands in Colombia, Ecuador, and Panama, streaked saltators are named for the heavy brown and white streaking across their breast and flanks. They inhabit forest edges, thickets, and secondary woodland, foraging on seeds and fruit in pairs and small groups. Listed as Least Concern but with a restricted range in Pacific lowland habitats increasingly threatened by agricultural expansion and deforestation. They produce characteristic rich whistled notes typical of saltators.
