Slant-Lines
Tetracis is a genus of geometrid moths in the subfamily Ennominae, established by Achille Guenée in 1858. The genus was revised taxonomically in 2010, when Synaxis was synonymized with Tetracis and three new western North American species were described. It currently comprises 13 recognized North American species. The common name 'Slant-Lines' refers to characteristic wing patterns visible in many species.
