Eulithis testata, the chevron, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in 1761. It is found in both the Palearctic and the Nearctic realms. In the Palearctic it ranges from Great Britain and Scandinavia, south to the Alps, east through Russia and the Russian Far East to Japan. In North America, it is found from Newfoundland to Vancouver Island and Alaska, south in the east to about New Jersey and in the west to Colorado. The specific name testata is derived from the Latin testa (baked stone) and refers to the base color of the wing.
