The latticed heath (Chiasmia clathrata) is a moth of the family Geometridae, belonging to the subfamily Ennominae, placed in the tribe Macariini. The genus was erected by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
The current placement of the latticed heath in the genus Chiasmia follows from the revision by Malcolm J. Scoble (2002) of the tribe Macariini, when he showed that true Semiothisa species were restricted to the Americas. There are a number of described subspecies. Molecular work has confirmed the placement of the species within Chiasmia.
