The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek geo γη or γαια 'the earth' and metron μέτρων 'measure' in reference to the way their larvae, or inchworms, appear to "measure the earth" as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, Biston betularia, which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests.
The Cidariini are the largest tribe of geometer moths in the subfamily Larentiinae. The Cidariini include many of the species known as "carpets" or, ambiguously, "carpet moths", and are among the few geometer moths that have been subject to fairly comprehensive cladistic study of their phylogeny.
