Coiban Mastuff Bat

The Coiban Mastuff Bat (Molossus coibensis) is a small free-tailed bat in the family Molossidae, named for Coiba Island off the Pacific coast of Panama, where specimens were first collected. Members of the genus Molossus are robust, fast-flying insectivores adapted to open-air foraging above the forest canopy and over water, characterised by narrow wings and a tail that extends beyond the patagium (wing membrane). Molossus coibensis inhabits lowland tropical forests and adjacent open habitats in Central America and northwestern South America, with confirmed records from Colombia, Ecuador, Venezuela, and Panama, indicating a distributional range that extends well beyond its type locality on Coiba Island. Like other mastiff bats, it roosts in crevices within buildings, rock faces, and hollow trees, emerging at dusk to pursue aerial insects at speed. The species feeds primarily on large beetles, moths, and other night-flying insects, typically hunted high above the forest. It is assessed as Least Concern by the IUCN based on its relatively wide range and tolerance of modified habitats. Molossus coibensis was long treated as a subspecies of Molossus molossus before being recognised as a distinct species based on morphological and molecular evidence. Ecological and life-history data specific to this taxon remain limited.

Common Grass-veneer

<em>Agriphila tristellus</em>, commonly known as the common grass veneer, is a small moth belonging to the genus Agriphila within the family Crambidae. This species occupies virtually all terrestrial and freshwater habitats, suggesting a broad ecological tolerance within its range. Its documented distribution includes Belgium, Denmark, Norway, and Sweden, indicating a range centered on northwestern and Scandinavian Europe. The species is assessed as Least Concern on the IUCN Red List, reflecting stable population status across its range. Common grass veneer moths typically inhabit grasslands and rough vegetation where larval foodplants are available. Biological traits of this species remain poorly documented in the scientific literature.
