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.

Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.
