The European species Euphyia unangulata was previously thought to be Holarctic. The name was therefore also applied to the North American populations. Malcolm J. Scoble et al. in Geometrid Moths of the World (1999) split them into distinct species.

The wingspan is 21–27 mm. Adults are on wing from April to September. There is one generation per year.

The larvae feed on various plants, including bedstraw, carnation, chickweed, elm, and mustard.^[2]
