Common Goldspeck

<em>Candelariella vitellina</em>, commonly known as common goldspeck, is a crustose lichen belonging to the genus Candelariella within the family Candelariaceae. This species inhabits ecosystems across Europe and North America and South America, reflecting a broad geographic tolerance suited to its saxicolous lifestyle. Its known range includes populations in four European countries, the United States in North America, and Colombia in South America. The species is assessed as Least Concern on the IUCN Red List, indicating that current population trends do not suggest elevated extinction risk. Common goldspeck typically colonizes exposed rock surfaces, bark, and other firm substrates in open environments where light availability supports its photosynthetic activity. Biological traits of this species remain poorly documented in the scientific literature.

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.
