Common Purple & Gold

The Common Purple and Gold, <em>Pyrausta purpuralis</em>, is a small moth in the family Crambidae, subfamily Pyraustinae, found across northern and western Europe including Belgium, Denmark, Norway, and Sweden. It is a distinctively patterned species with rich purple-crimson forewings marked by bright golden-yellow spots and patches, making it one of the more visually striking micro-moths of the European fauna. The species typically inhabits calcareous grasslands, chalk downs, coastal cliffs, and heathlands where its larval host plants, particularly species of wild thyme (<em>Thymus</em>) and marjoram (<em>Origanum</em>), are abundant. The caterpillars typically feed on the leaves and stems of these aromatic herbs in sheltered, sun-exposed sites. Adults fly in one or two generations per year, typically from late spring through summer, and are diurnal, often seen nectaring on flowers in warm sunshine. <em>Pyrausta purpuralis</em> is assessed as Least Concern on the IUCN Red List given its distribution across suitable habitats in Europe. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
