Common Marbled Carpet

<em>Dysstroma truncata</em>, the common marbled carpet, is a geometrid moth in the family Geometridae distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List, reflecting stable populations across its wide temperate range. The species is typically found in woodland, hedgerow, and garden habitats where its larval food plants are present. Its wings display complex, marbled patterns in shades of brown, grey, and white, providing effective camouflage against tree bark and leaf litter. Adults are typically nocturnal and are recorded from spring through autumn, with multiple generations possible in warmer parts of its range. Larvae feed on a variety of deciduous plants including bilberry, heather, and various shrubs. The common marbled carpet is a familiar species to moth recorders across temperate Europe and North America, where it is frequently encountered at light traps. Its widespread distribution and habitat generalism contribute to its secure conservation status across both continents.
