With luck
About 10% of wildlife watchers report a European Yellow Loosestrife Bee sighting in Helsinki on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 233rd 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.
July and August
In those months about 10% of wildlife watchers report a European Yellow Loosestrife Bee in Helsinki on a given day, against under 5% in September to June, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most European Yellow Loosestrife Bee sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 cities where we can rate European Yellow Loosestrife Bee sightings, Helsinki ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Hamburg (Germany, about 10%) and Warsaw (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the European Yellow Loosestrife Bee is recorded against all the insects logged in Helsinki (27 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.
