Choco Yellow-shouldered Bat

The Choco Yellow-shouldered Bat (Sturnira koopmanhilli) is a medium-sized frugivorous bat in the family Phyllostomidae, endemic to the Chocó biogeographic region of northwestern South America, where it occurs in the humid forests of the Pacific slope of Colombia and adjacent Ecuador. It belongs to the genus Sturnira — the yellow-shouldered bats — characterised by males bearing distinctive yellowish, orange, or reddish shoulder glands (from which the group's name derives), robust bodies, and rounded ears. Like all Sturnira, this species is primarily frugivorous, consuming a wide range of small, soft fruits from pioneer and forest trees, and plays an important role as a seed disperser in disturbed forest patches and forest edges. The diet of Solanaceae (nightshade family) fruits is particularly typical of the genus, and Sturnira bats are considered the primary dispersers of many pioneer Solanum species in Neotropical secondary succession, contributing directly to forest regeneration. The IUCN classifies the Choco Yellow-shouldered Bat as Data Deficient, reflecting significant uncertainty about the species' distribution limits, population size, and ecological requirements. The Chocó region continues to experience rapid deforestation, which threatens frugivorous bat diversity even where individual species lack adequate data for formal threat assessment.

Große Veränderliche Grasbüscheleule

The clouded bordered brindle (Apamea crenata) is a noctuid moth in the family Noctuidae found across temperate Europe and across northern Asia to Japan. The adult wingspan measures approximately 38–45 mm, with intricately patterned grey-brown and buff forewings bearing subtle cross-lines, a scalloped (crenate) outer margin giving the species its name, and distinctive reniform and orbicular markings characteristic of the Apamea genus. Adults fly in one generation from May to July, visiting flowers for nectar at night. The larvae feed internally within the stems and roots of grasses, particularly Brachypodium and other coarse grass species in woodland rides, woodland margins, and rough grassland habitats. Overwintering occurs as a larva within plant stems. Like many grass-feeding noctuids, the clouded bordered brindle requires structural diversity in its grassland and woodland edge habitats, with areas of tall, tussocky grasses providing both larval foodplants and adult shelter. Population trends in parts of its European range reflect changes in land management affecting coarse grassland and woodland ride quality.
