Rare
Under 5% of wildlife watchers report a Scarce Tortoiseshell sighting in Kyiv on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 591st most-seen of the 753 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.
March and June
In those months about 10% of wildlife watchers report a Scarce Tortoiseshell in Kyiv on a given day, against under 5% in April–May and July–February, the lowest months.

Across all the parks we cover, that three-hour window holds the most Scarce Tortoiseshell sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 11
Of the 11 cities where we can rate Scarce Tortoiseshell sightings, Kyiv ranks 10th at under 5%. The best odds are in Nizhny Novgorod (Russia, about 20%), Novosibirsk (Russia, about 10%) and Moscow (Russia, about 10%).

GBIF citizen-science records
It is estimated from how often the Scarce Tortoiseshell is recorded against all the insects logged in Kyiv (6 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.
