Colombian Oldfield Mouse

<em>Thomasomys dispar</em>, commonly known as the Colombian Oldfield Mouse, is a small rodent species belonging to the genus <em>Thomasomys</em> within the family Cricetidae. This species is classified as Data Deficient, indicating that insufficient information is currently available to evaluate its conservation status with confidence. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Thomasomys</em> are typically associated with high-altitude Andean habitats, including páramo grasslands, shrublands, and montane forest edges, where they occupy ground-level microhabitats and burrow in soft soils. These mice are generally omnivorous, consuming seeds, plant material, and invertebrates, though specific dietary data for <em>Thomasomys dispar</em> have not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification highlights the need for targeted surveys in Colombian Andean regions to determine population size, distribution, and the ecological requirements of this poorly known rodent.

Common Grey

<em>Scoparia ambigualis</em>, commonly known as the common grey, is a small moth belonging to the genus Scoparia within the family Crambidae. This species inhabits virtually all terrestrial and freshwater habitats and has a documented range across Belgium, Denmark, Norway, and Sweden in northwestern and Scandinavian Europe. Common grey is assessed as Least Concern on the IUCN Red List. The species is typically encountered in a variety of open and semi-open habitats including heathland, grassland, and woodland edges, where its cryptically patterned grey and white forewings provide effective camouflage at rest. Adults are typically nocturnal and are attracted to light. Biological traits of this species remain poorly documented in the scientific literature.
