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.

comitan juniper

<em>Juniperus comitana</em>, commonly known as the Comitan Juniper, is a coniferous tree or shrub in the family Cupressaceae, native to Central America. This species is classified as Endangered on the IUCN Red List, reflecting significant population pressures across its restricted range. It typically inhabits temperate and boreal forest environments at higher elevations, often occurring in mountainous regions where cooler, drier conditions prevail. Like other members of the genus Juniperus, it often plays an important ecological role in its native habitat, providing cover and food resources for local wildlife. The Comitan Juniper faces ongoing threats from habitat loss due to deforestation, agricultural expansion, and land-use change within its limited geographic distribution. Its specialized requirements for higher-elevation forest environments make it particularly vulnerable to habitat degradation and climate-related shifts. Conservation efforts are critical to prevent further population decline of this Endangered conifer. Biological traits of this species remain poorly documented in the scientific literature.
