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 Cicadabird

<em>Edolisoma tenuirostre</em>, commonly known as the common cicadabird, is a bird species with a documented record from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often associated with forest canopies, forest edges, and wooded areas in its native range across the Australasian region. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. Common cicadabird belongs to the genus <em>Edolisoma</em> within the family Campephagidae. It is a slender, cuckoo-shrike-like bird that typically forages for insects and other invertebrates in the forest canopy, often remaining inconspicuous due to its cryptic coloration and preference for the upper tree strata. Males and females typically exhibit marked sexual dimorphism in plumage. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. The species' broad native range across Australasia contributes to its currently stable conservation status.
