The Common Field Horsetail (<em>Equisetum arvense</em>) is a vascular plant belonging to the genus Equisetum within the family Equisetaceae. It is one of the most widespread and recognisable of the horsetail species, characterised by its jointed, hollow stems and whorls of slender branches. The species is found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, spanning the Afrotropic and Palearctic biogeographic realms. Its geographic distribution is exceptionally broad, encompassing Africa including Mauritius, Asia including Iran and Taiwan, nine European countries, North America including Canada, Mexico, and the United States, Oceania including Australia and New Zealand, and South America including Brazil. <em>Equisetum arvense</em> is assessed as Least Concern on the IUCN Red List. The plant often colonises disturbed soils and is considered a persistent weed in agricultural settings. Biological traits beyond its distinctive morphology remain poorly documented in the scientific literature.

Hespérie délicate

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.
