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 Neacomys

<em>Neacomys spinosus</em>, the common neacomys or spiny neacomys, is a small rodent in the family Cricetidae found in South America. This ground-dwelling mouse is characterized by its distinctively spiny fur, an adaptation that may provide protection against predators. <em>Neacomys spinosus</em> typically inhabits tropical lowland and montane forests, forest edges, and adjacent scrubby vegetation in northwestern South America, with its geographic range including Colombia and surrounding countries. The species forages on the forest floor and in low vegetation, and is believed to consume seeds, plant material, and invertebrates, although specific dietary data are limited. It is currently assessed as Least Concern by the IUCN, with populations considered stable across its range, though ongoing deforestation in the Amazonian and Andean foothills may present long-term threats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species across its full range. <em>Neacomys spinosus</em> plays a role in seed dispersal and forms part of the prey base for small mammalian and avian predators in its tropical forest ecosystems.
