Gemeiner Blütenspanner

The Common Pug, <em>Eupithecia vulgata</em>, is a moth in the family Geometridae, subfamily Larentiinae, found across northern and central Europe including Belgium, Denmark, Norway, and Sweden. It is a small, pale gray moth with a characteristic darker central band and fine crosslines on the forewings, displaying the cryptic wing patterning typical of the Eupithecia genus. The species typically inhabits gardens, hedgerows, woodland edges, scrublands, and urban green spaces, where its larval host plants are found. The caterpillars are polyphagous and typically feed on the flowers and developing seeds of a variety of herbaceous and woody plants, including species of Asteraceae, hawthorn, and other common shrubs and herbs. Adults are nocturnal and are attracted to light, flying in one or two generations per year depending on latitude and climate. <em>Eupithecia vulgata</em> overwinters as a pupa in the soil or leaf litter. The species is assessed as Least Concern on the IUCN Red List given its broad distribution and adaptability to human-modified habitats. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
