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.
Common Eastern Wildrye
<em>Elymus virginicus</em>, the common eastern wildrye, is a native North American grass in the family Poaceae, currently not evaluated by the IUCN Red List. The species is documented in Denmark, Sweden, and the United States, and typically inhabits grasslands, wetlands, forests, and cultivated lands across its range in eastern and central North America. It is a cool-season, perennial bunchgrass that typically grows in moist to mesic habitats including riverbanks, floodplain woodlands, forest understories, and moist prairies. <em>Elymus virginicus</em> is recognized by its distinctive nodding seed heads with stiff, curved awns and is among the most widely distributed wild rye grasses in North America. The species provides important ecosystem services as a native ground cover, stabilizing streambanks and riparian soils against erosion, and offering habitat and food resources for grassland birds, small mammals, and invertebrates. Common eastern wildrye is also valued in ecological restoration projects for its adaptability to a range of soil conditions and its ability to establish quickly in disturbed habitats. As a forage grass, it is moderately palatable to livestock and wildlife. Biological traits of this species remain poorly documented in the scientific literature.
