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.

Collared Brushturkey

<em>Talegalla jobiensis</em>, the Collared Brushturkey, is a megapode in the family Megapodiidae. This species is assessed as Least Concern on the IUCN Red List. It is native to New Guinea, occurring in lowland and hill forests where it is typically found in dense rainforest habitats. Megapodes are notable for their unique thermoregulatory breeding strategy: instead of incubating eggs with body heat, they construct large mounds of organic material in which eggs are buried and incubated by the heat generated by decomposing vegetation. <em>Talegalla jobiensis</em> belongs to a group of brushturkeys restricted to the Australasian region. Diet information typically includes invertebrates, seeds, and fallen fruit foraged from the forest floor, as is common in megapodes, though specific diet data for this species are not enumerated in available records. Biological measurements including average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects stable populations within its New Guinea range.
