Climbing Flat-bean

Climbing Flat Bean, Vigna unguiculata subsp. sesquipedalis, commonly known as the Yard-long Bean or Asparagus Bean, is a vigorous climbing legume in the family Fabaceae widely cultivated across tropical and subtropical Asia for its extraordinarily long, edible pods. The pods, reaching up to 60–100 cm in length, are harvested when young and tender and are used extensively in Chinese, Southeast Asian, and South Asian cuisine. The species climbs trellises and poles using tendril-like, twining stems, producing purplish-white flowers that develop into the characteristic pendulous, slender bean pods. Like other Vigna species, it fixes atmospheric nitrogen through symbiotic bacteria in root nodules, improving soil fertility. Climbing Flat Bean is a warm-season crop requiring full sun, high temperatures, and adequate moisture, making it well suited to humid tropical and monsoon climates. It is an important food crop providing protein and vitamins for rural communities across Asia and is cultivated as a commercial vegetable in many tropical countries. The species is also grown in tropical America and Africa. Being a domesticated cultivar complex, its conservation status is not formally assessed in terms of wild populations, though the preservation of genetic diversity in cultivated landraces is an agricultural priority.

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.
