Chroococcus minimus is a species of cyanobacteria in the family Chroococcaceae, representing one of the smaller-celled members of the genus, as the specific epithet indicates. Chroococcus is a cosmopolitan cyanobacterial genus found across a wide range of aquatic and moist terrestrial habitats globally. The cells of Chroococcus minimus are spherical, very small in diameter, and occur in pairs or tetrads enclosed within a thin, often inconspicuous mucilaginous sheath. Despite their miniature scale, these organisms are photosynthetically active and contribute to primary production in their aquatic environments. Small-celled cyanobacteria like Chroococcus minimus may dominate the picoplankton fraction of oligotrophic freshwater bodies, where their small cell volume provides a favorable surface area to volume ratio for nutrient uptake in nutrient-limited conditions. Chroococcus minimus has been documented from freshwater habitats in Europe and elsewhere. Identification of small-celled Chroococcus species is challenging due to overlapping morphological characteristics and the influence of environmental conditions on cell dimensions. Molecular phylogenetic studies have substantially revised the taxonomy of coccoid cyanobacteria. The species has not been assessed by the IUCN.

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.
