Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Common gorse

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and deserts and xeric shrublands, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Coastal Silver-stiletto

Coastal silver stiletto (Acrosathe annulata) is a slender robber fly in the family Therevidae, native to northwestern Europe, including the United Kingdom, France, the Netherlands, Belgium, and Scandinavia. Adults are found on coastal sand dunes and sandy heathland, where they perch on bare sand to ambush small flying insects. Stiletto flies in the family Therevidae are characterised by a slender body, long pointed abdomen, and predatory habits; adults prey on a variety of small dipterans and other flying insects during warm, sunny periods. Larvae develop in sandy soil, where they are also predatory, feeding on other invertebrate larvae. Acrosathe annulata is a habitat specialist restricted to open, sandy coastal habitats with sparse vegetation—environments that have declined substantially across northwestern Europe due to dune stabilisation, recreational disturbance, and the cessation of traditional dune management. The IUCN lists it as Least Concern, though regional conservation bodies in the United Kingdom have flagged population declines. It is considered an indicator of high-quality coastal sand dune habitats and is monitored through national invertebrate surveys.

Common gorse

<em>Ulex europaeus</em>, commonly known as common gorse, is a spiny evergreen shrub belonging to the genus Ulex within the legume family Fabaceae. The species occupies a remarkable breadth of habitat types, including tropical and subtropical moist broadleaf forests, dry broadleaf forests, and deserts and xeric shrublands, among at least eight recognized biome categories. Its global range is exceptionally wide, spanning Africa, Asia, Europe, North America, Oceania, and South America, with records from numerous countries on each continent. Notably introduced and sometimes invasive outside its European origin, common gorse typically colonizes disturbed lands, heathlands, and coastal scrub. The species is assessed as Least Concern on the IUCN Red List. Biological traits of this species remain poorly documented in the scientific literature.
