common carpet

<em>Epirrhoe alternata</em>, commonly known as the common carpet, is a moth species found across Europe, Canada, and the United States. It typically inhabits all terrestrial and freshwater environments, often occurring in woodland edges, gardens, hedgerows, and areas where its larval host plants are abundant. The species is classified as Least Concern on the IUCN Red List, reflecting its broad distribution and generally stable populations. The common carpet belongs to the genus <em>Epirrhoe</em> within the family Geometridae. As a geometer moth, it is characterized by its distinctive wing patterns, which feature alternating light and dark banding that gives rise to its common name. The larvae typically feed on plants in the family Rubiaceae, particularly bedstraws (<em>Galium</em> species), and adults are often observed resting with wings spread flat against vegetation or bark. Biological traits such as average lifespan, wingspan, and body mass of this species remain poorly documented in the scientific literature. The species is a common component of temperate moth communities across its range.
