Rare
Under 5% of wildlife watchers report a Balsam Carpet sighting in Moscow on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 637th most-seen of the 1111 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Balsam Carpet in Moscow on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Balsam Carpet sightings with a recorded time, and about 7 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 Balsam Carpet sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Balsam Carpet is recorded against all the insects logged in Moscow (11 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.
