Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.

Nitzschia intermedia is a pennate diatom in the family Bacillariaceae found in freshwater to slightly brackish habitats, where it inhabits both benthic and planktonic niches. Its elongate frustule with a keeled raphe and fine transapical striae is typical of the large genus Nitzschia. It serves as a bioindicator of moderate organic enrichment and nutrient levels in aquatic monitoring programs.
