Chokecherry

The Chokecherry (Prunus virginiana) is a widespread, suckering shrub or small tree in the family Rosaceae, native throughout most of North America from Alaska and the Yukon south to Georgia and Baja California, with naturalised populations in parts of Europe. It produces clusters of small white flowers in elongated racemes in spring, followed by dark red to near-black drupes (chokecherries) that are astringent and bitter when raw due to high tannin content but become palatable after cooking and are widely used for jams, jellies, syrups, and wines. The common name chokecherry alludes to the choking sensation caused by eating unripe or raw fruit. All parts of the plant except the ripe flesh contain cyanogenic glycosides — primarily amygdalin — which can release hydrogen cyanide and are toxic to humans and livestock if consumed in quantity. The species is highly adaptable, colonising roadsides, forest edges, disturbed ground, and riparian areas across a wide range of soil types and climates. It is an important wildlife plant throughout its range, providing food for numerous birds (particularly thrushes, waxwings, and grouse) and mammals (bears, deer, raccoons). The IUCN lists it as Not Evaluated. Chokecherry is also an important cultural plant for many Indigenous peoples of North America.

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.
