Rundflügel-Kätzche

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.
