clay triple-lines

The Clay Triple-lines, Cyclophora linearia, is a geometrid moth in the family Geometridae found across Europe and temperate Asia, inhabiting deciduous woodland, hedgerows, and scrubby areas where its larval host plant beech (Fagus sylvatica) is present. The forewings are pale clay-buff to cream, crossed by three distinct darker brown or ochreous lines from which the common name derives, with a small darker discal spot. The hindwings are similarly patterned but slightly paler. The species is well camouflaged at rest on bark and dead wood. Adults are crepuscular and nocturnal, flying in two generations per year in much of its range, with adults on the wing in spring and again in summer. The larvae feed on the young leaves of beech trees, and the species is strongly associated with mature beech woodland throughout its range. As beech woodland becomes increasingly threatened by climate change, drought stress, and changing forest management practices across Europe, specialist beech-associated insects like the Clay Triple-lines may face habitat contractions. The species is currently widespread and not considered globally threatened, but national populations show variation in abundance tied to the health of beech forest habitats.
