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 alder midget

<em>Phyllonorycter rajella</em>, commonly known as the Common Alder Midget, is a small moth in the family Gracillariidae. This species is assessed as Least Concern on the IUCN Red List and is distributed across Europe, with records from countries including Germany, the United Kingdom, and several Scandinavian nations. As its common name suggests, the larval stage of this moth is closely associated with alder trees (Alnus species), within whose leaves the caterpillars create characteristic leaf mines. Adult moths are small with intricately patterned wings typical of gracillariid moths, often featuring metallic or golden markings. The species typically completes one or more generations per year, with adults emerging in spring and summer. Leaf-mining activity by the larvae produces distinctive blotch or tentiform mines visible on the undersides of alder leaves. The Common Alder Midget is generally considered a specialist of riparian and wetland habitats where alder trees commonly grow. Biological traits of this species remain poorly documented in the scientific literature.
