Coastal Dendrobium

Dendrobium litorale, the coastal dendrobium, is an epiphytic orchid in the family Orchidaceae native to lowland coastal forests and mangrove margins across the Pacific island region, including Papua New Guinea, the Solomon Islands, and adjacent island groups. The genus Dendrobium is one of the largest in the Orchidaceae, comprising over 1,800 described species distributed from tropical Asia through Australasia and the Pacific, and includes numerous horticulturally important species cultivated worldwide. Dendrobium litorale grows as an epiphyte attached to tree branches and trunks in humid coastal forest environments, including forest-mangrove transition zones subject to salt spray and tidal influence that few other orchids can tolerate. The pseudobulbs store water and nutrients, enabling survival during intermittent dry periods. Flowers are typically small to medium-sized with white or pale coloring and complex labellum structures that guide pollinators, often specific bee species, into contact with pollen. The species is classified as Least Concern by the IUCN. Coastal lowland forests across the Pacific face significant ongoing pressure from logging, oil palm conversion, and human settlement expansion, threatening the specific forest-mangrove habitats this coastal orchid requires.

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.
