Larva elongate, transversely wrinkled, with two minute warts on the 8th abdominal segment: yellowish brown clouded with grey and with reddish. The larvae feed on various deciduous and coniferous trees. On birch, beech, oak, etc. The pupa hibernates. Wikipedia →

Rare
Under 5% of wildlife watchers report a Square Spot sighting in Moscow on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 774th most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Square Spot in Moscow on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Square Spot sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Square Spot sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Square Spot that you can see in Moscow (family Geometridae, Geometer Moths) are Winter Moth (about 10%), Common Carpet Moth (about 10%) and Northern Winter Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Square Spot is recorded against all the insects logged in Moscow (8 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.
