The common carpet or white-banded toothed carpet (Epirrhoe alternata) is a moth of the family Geometridae. It is found throughout the Palearctic and the Near East. In North America it ranges across the northern tier of the United States plus every province and territory of Canada.


The wingspan is 27–30 mm. The forewings vary from grey to black, marked with white fascia, giving a striped appearance. The hindwings are paler grey with white fascia. Northern races tend to be paler overall. One or two broods are produced each year, and the adults may be seen any time from May to September [1]. The species flies at night and is attracted to light.

The larva is generally brown or green but is very variable in its markings. It feeds on bedstraw. The species overwinters as a pupa.
