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.

Collared Babbler

<em>Gampsorhynchus torquatus</em>, the Collared Babbler, is a bird in the family Timaliidae or Leiothrichidae, depending on the classification authority. This species is assessed as Least Concern on the IUCN Red List. It is native to South and Southeast Asia, occurring in countries such as India, Bangladesh, Myanmar, Thailand, and the Malay Peninsula, inhabiting bamboo thickets, forest edges, and scrub habitats. The genus <em>Gampsorhynchus</em> comprises a small number of babbler species known for their distinctive calls and social behavior. The Collared Babbler is named for the collar pattern in its plumage. Diet information, population estimates, and biological measurements including average length, weight, and lifespan are not specified in the available data. Biological traits of this species remain poorly documented in the scientific literature. The species occupies aerial, terrestrial, and aquatic environments within its range. Its Least Concern designation reflects that populations are not currently considered at elevated extinction risk, though habitat degradation in its Southeast Asian range may pose longer-term concerns.
