Rare
Under 5% of wildlife watchers report a Brindled Flat-Body sighting in Moscow on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 366th 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 Brindled Flat-Body in Moscow on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Brindled Flat-Body sightings, Moscow ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Nizhny Novgorod (Russia, under 5%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Brindled Flat-Body is recorded against all the insects logged in Moscow (26 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.
