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.

Rare
Under 5% of wildlife watchers report a Latticed Heath sighting in London on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 842nd most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Latticed Heath in London on a given day, against under 5% in September to July, the lowest months.
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.
26th of 27
Of the 27 cities where we can rate Latticed Heath sightings, London ranks 26th at under 5%. The best odds are in Birmingham (United Kingdom, about 10%), Berlin (Germany, about 10%) and Vienna (Austria, about 10%).
Same family: Geometridae
The closest relatives of the Latticed Heath that you can see in London (family Geometridae, Geometer Moths) are Riband Wave (about 20%), Least Carpet (about 20%) and Double-Striped Pug (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 London (17 verified sightings), 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.
