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 Spiny Digger Wasp

<em>Oxybelus uniglumis</em>, commonly known as the common spiny digger wasp, is a small solitary wasp in the family Crabronidae, widespread across Europe, North Africa, and parts of western Asia. This species typically inhabits sunny, open areas with sandy or loose soil, including sand dunes, sandy heathlands, path edges, and sparsely vegetated ground where females excavate burrows for nesting. Its geographic range extends from the British Isles and Scandinavia across continental Europe to the Mediterranean, with additional populations recorded across North Africa and into central Asia. Classified as Least Concern on the IUCN Red List, <em>Oxybelus uniglumis</em> is among the more commonly encountered digger wasps in European sandy habitats. The species is a specialised predator of flies, particularly small dipterans from families such as Muscidae and Calliphoridae, which are paralysed and carried back to the burrow impaled on the female's sting to provision larval cells. This behaviour of impaling prey on the sting for transport is a distinctive characteristic of the genus Oxybelus. Biological traits such as average lifespan in years, precise body length measurements, and body weight remain poorly documented for this species. Adults are typically active from late spring through late summer.
