With luck
About 10% of wildlife watchers report a Ruddy Darter sighting in Helsinki on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 838 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Ruddy Darter in Helsinki on a given day, against under 5% in November to July, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Ruddy Darter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 32
Of the 32 cities where we can rate Ruddy Darter sightings, Helsinki ranks 18th at about 10%. The best odds are in Kyiv (Ukraine, about 20%), Brussels (Belgium, about 20%) and Warsaw (Poland, about 20%).

GBIF citizen-science records
It is estimated from how often the Ruddy Darter is recorded against all the insects logged in Helsinki (42 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.
