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.

Coffee

Coffee (Coffea arabica) is a woody shrub or small tree in the family Rubiaceae, native to the montane forests of Ethiopia and Yemen, where it was discovered and first cultivated before spreading globally to become one of the world's most economically important crops. Plants grow 2–10 metres tall in the wild but are typically pruned to 2–3 metres in cultivation, producing glossy elliptical leaves and clusters of fragrant white flowers followed by cherry-like drupes that ripen from green through yellow to deep red. Each fruit contains two seeds—the coffee beans—surrounded by layers of sweet pulp, parchment, and silver skin. Coffea arabica is a diploid tetraploid (2n = 44) that produces smoother, more aromatic coffee than its sibling species Coffea canephora (Robusta). Wild populations in Ethiopian highland forests represent an important reservoir of genetic diversity for the global coffee industry and are threatened by deforestation and climate change, which is altering the geographic suitability of arabica cultivation. Commercial plantations extend from Colombia, Brazil, and Central America through East Africa to India, Indonesia, and Vietnam. As a shade-tolerant understorey plant in its native montane habitat, Coffea arabica supports biodiversity in agroforestry systems. Despite its vast cultivation, wild arabica populations face significant conservation concern.
