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.

Possible
About 30% of wildlife watchers report a Latticed Heath sighting in Biebrza National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 97 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Latticed Heath in Biebrza National Park on a given day, against under 5% in March–April and August–September, the lowest months. December has too few records to rate.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Latticed Heath sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 18 parks where we can rate Latticed Heath sightings, Biebrza National Park has the highest daily chance: about 30%. Next come Białowieża National Park (Poland, about 20%) and Aigüestortes National Park (Spain, about 20%).
Same family: Geometridae
The closest relatives of the Latticed Heath that you can see in Biebrza National Park (family Geometridae, Geometer Moths) are Common Heath (about 20%), Lewes Wave (about 20%) and Black-Veined Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Latticed Heath is recorded against all the insects logged in Biebrza National Park (12 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.
