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.

Leatherback Sea Turtle

The leatherback is the largest living turtle and the fourth-heaviest reptile. Unlike other turtles, it has a soft, leathery shell.
