With luck
About 10% of wildlife watchers report a European Yellow Loosestrife Bee sighting in Warsaw on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 208th most-seen of the 580 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
In that month about 20% of wildlife watchers report a European Yellow Loosestrife Bee in Warsaw on a given day, against under 5% in September to June, the lowest months. That is one of Warsaw's wettest months, with about 75 mm of rain against 40 mm in February.
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, Warsaw ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Hamburg (Germany, 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 Warsaw (24 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.
