In 3 days ~20% in a week ~50%
The vagrant darter, or moustached darter, (Sympetrum vulgatum) is a European dragonfly. The species takes its English name from its habit of occasionally appearing as a rare vagrant north of its normal range. However, it is likely to be under-recorded because it is very similar to the common darter (S. striolatum).
The species is common in central and northeast Europe. It breeds in standing water. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Vagrant Darter is recorded against all the insects logged in Kazan (37 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.
