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.

GBIF citizen-science records
It is estimated from how often the Latticed Heath is recorded against all the insects logged in Mercantour National Park (13 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
