Chydorus
Chydorus is a genus of small benthic-littoral cladocerans in the family Chydoridae, established by William Elford Leach in 1816. Species in this genus are characterized by rounded, often reticulated carapaces and are among the most common anomopods in freshwater systems worldwide. The genus exhibits cosmopolitan distribution with multiple centers of diversification in Europe and Asia, and includes ecologically significant species such as Chydorus sphaericus, which dominates eutrophic waters and plays important roles in food web dynamics involving cyanobacteria.
Cricotopus
non-biting midges
Cricotopus is a large and diverse genus of non-biting midges in the family Chironomidae, subfamily Orthocladiinae. Species occupy a wide range of freshwater and estuarine habitats globally, from pristine glacial streams to degraded urban waterways. Some species are specialized stem miners of aquatic plants, including C. lebetis which targets invasive hydrilla. The genus includes species with documented mutualistic relationships with cyanobacteria (Nostoc), as well as species used in biomonitoring and ecotoxicological research.
Paracoenia bisetosa
Paracoenia bisetosa is a shore fly in the family Ephydridae. Its immature stages develop in microbial mats composed of cyanobacteria and algae. The species was first described as Coenia bisetosa by Coquillett in 1902.
