Habitat & Geographic Range

Common Spiny Digger Wasp

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Eurasian Skylark

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical moist broadleaf forests spanning the Australasia and Oceanian realms.

Range

Widely distributed across Europe (5 countries), North America (Canada, United States), and Oceania and the Pacific (Australia, New Zealand). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Eurasian Skylark

Celebrated across European literature and poetry for its complex, melodious song sung on the wing during spectacular display flights, Eurasian skylarks soar vertically hundreds of meters above open farmland, grassland, and heathland across Europe and Asia while producing an uninterrupted torrent of song lasting up to an hour. Males can produce over 700 distinct song phrases. Once enormously abundant across European farmland, skylark populations have declined over 70% since 1970 due to agricultural intensification.
