With luck
About 10% of wildlife watchers report a European Orchard Bee sighting in Pyrénées National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 521st most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a European Orchard Bee in Pyrénées National Park on a given day, against under 5% in May to January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most European Orchard Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 parks where we can rate European Orchard Bee sightings, Pyrénées National Park ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Bavarian Forest National Park (Germany, about 10%), Cévennes National Park (France, about 10%) and Fertő-Hanság National Park (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the European Orchard Bee is recorded against all the insects logged in Pyrénées National Park (16 verified sightings from 2019 to 2026), 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.
