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 Lime

<em>Tilia europaea</em>, the common lime or European linden, is a large deciduous tree in the family Malvaceae, occurring naturally as a hybrid between <em>Tilia cordata</em> and <em>Tilia platyphyllos</em>. It is widely distributed across Europe and has been introduced to North America, where it is commonly planted as a street and park tree. The common lime typically grows in temperate broadleaf forests and urban environments, reaching considerable heights and living for several centuries. It produces fragrant, pale yellow flowers in summer that are highly attractive to bees and other pollinators, earning it a prominent role in honey production. The species has not been assessed for the IUCN Red List. Its wood is valued for carving and musical instrument manufacture, while its flowers and leaves have traditional uses in herbal medicine. Common lime is particularly notable for producing abundant basal sprouts and epicormic shoots, a characteristic that makes it useful for coppicing and pollarding in traditional land management practices across Europe and North America.
