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.

common quaker

The Common Quaker, <em>Orthosia cerasi</em>, is a moth in the family Noctuidae widely distributed across northern and western Europe, with records from Belgium, Denmark, Norway, and Sweden. It is a medium-sized noctuid moth with pale brownish-gray to ochreous forewings marked by two rounded spots, the reniform and orbicular stigmata, and a subtly scalloped outer margin, displaying the understated cryptic patterning characteristic of early-spring Orthosia species. The Common Quaker is one of the earliest moths to fly in spring, typically emerging in February and March when temperatures barely rise above freezing, and is a regular visitor to light traps and sallow blossom. The species typically inhabits deciduous woodland, hedgerows, orchards, and gardens where broadleaved trees are available. The caterpillars are polyphagous, typically feeding on the foliage of oaks, hawthorns, birches, and other deciduous trees and shrubs. <em>Orthosia cerasi</em> overwinters as a pupa in the soil. It is assessed as Least Concern on the IUCN Red List given its wide distribution and abundance in suitable woodland habitats across its European range. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
