Clustered Feather-moss

Rhynchostegium confertum, the clustered feather moss, is a pleurocarpous moss in the family Brachytheciaceae distributed across Europe, where it grows on rocks, walls, tree bases, and compacted soil in a variety of habitats including woodland, gardens, churchyards, and urban environments. The plants form dense, bright green to yellowish-green mats with pinnately branched stems bearing small, ovate-lanceolate leaves. This species is listed as Near Threatened by the IUCN, reflecting concerns about population declines in parts of its European range, possibly related to air quality changes, habitat alteration, and drought. Brachytheciaceae mosses are common components of temperate and boreal flora, and R. confertum is one of the more urban-tolerant members of the family, occurring even in heavily built environments. Like all pleurocarpous mosses, R. confertum spreads vegetatively through fragmentation and produces spores from upright, slender sporophytes during the reproductive season. It contributes to moisture retention on substrates and provides microhabitats for invertebrates in urban and semi-natural environments.

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.
