Columbus grass

<em>Sorghum almum</em>, commonly known as Columbus grass, is a robust perennial grass in the family Poaceae. It thrives in disturbed habitats, roadsides, agricultural margins, and open grasslands, demonstrating a strong preference for warm climates and well-drained soils. The species has been introduced and naturalized across many tropical and subtropical regions beyond its original South American range, and is cultivated in parts of Africa, Asia, and Australia as a forage grass. It produces tall, erect culms that can reach several meters in height, bearing broad leaf blades and open, branching panicles with numerous spikelets. Columbus grass is valued for livestock fodder but is also regarded as an invasive weed in certain agricultural contexts due to its vigorous growth and capacity for vegetative spread via rhizomes. Biological metrics including lifespan, length, and weight data are not available in the current record.

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.
