Bare-legged Swiftlet

The Bare-legged Swiftlet (Aerodramus nuditarsus) is a species in the genus Aerodramus. It is currently classified as Least Concern on the IUCN Red List. Typically found in various aerial, terrestrial, and aquatic environments.

Cinerous Groundling

The cinerous groundling (Bryotropha terrella) is a small moth in the family Gelechiidae, distributed across Europe including Britain, Scandinavia, and much of continental Europe. It inhabits dry, open habitats such as heathland, sand dunes, chalk grassland, and dry grassland margins, where its larvae feed on mosses and low-growing plants close to the soil. The adult moth has pale straw-colored to gray-brown forewings with indistinct markings, providing camouflage in its dry, open habitat. Like many gelechiid moths, Bryotropha terrella is a small, inconspicuous species that is frequently under-recorded due to the challenges of identifying micro-moths. The species is classified as Least Concern, with populations found across a wide range of European countries with suitable dry, open habitat. Its larval association with mosses and low vegetation makes it dependent on short, open sward conditions—habitats that have declined in parts of Europe due to agricultural intensification, scrub encroachment following the abandonment of traditional grazing, and afforestation. Moth surveys using light traps and careful examination of micro-lepidoptera have expanded knowledge of this and related gelechiid species' distributions. Conservation of dry heathland and chalk grassland habitats benefits a wide range of invertebrates including this species.
