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 Fig

The Common Fig (<em>Ficus carica</em>) is a deciduous tree or large shrub belonging to the genus Ficus within the family Moraceae. It is widely recognised for its broad, lobed leaves and distinctive edible fruit, the fig, which is a syconium — a fleshy, hollow structure enclosing numerous small flowers. The species is typically found in diverse terrestrial habitats from tropical forests to temperate regions, and has a wide geographic distribution spanning Africa including eight countries, Asia including Qatar, Taiwan, and Yemen, 18 European countries, North America including Canada and the United States, Oceania and the Pacific including five countries, and South America including five countries. <em>Ficus carica</em> has not been evaluated under IUCN criteria. It has been cultivated for thousands of years as a food crop across the Mediterranean region and western Asia, and is considered one of the earliest domesticated plants. Pollination typically involves a specialised mutualistic relationship with fig wasps. Biological traits including average lifespan and body dimensions in the wild remain poorly documented in the scientific literature.
