Bombus ruderatus
In 3 days ~10% in a week ~20%
Bombus ruderatus, the large garden bumblebee or ruderal bumblebee, is a species of long-tongued bumblebee found in Europe and in some parts of northern Africa. This species is the largest bumblebee in Britain and it uses its long face and tongue to pollinate hard-to-reach tubed flowers. Bumblebees are key pollinators in many agricultural ecosystems, which has led to B. ruderatus and other bumblebees being commercially bred and introduced into non-native countries, specifically New Zealand and Chile. Since its introduction in Chile, B. ruderatus has spread into Argentina as well. Population numbers have been declining and it has been placed on the Biodiversity Action Plan to help counteract these declines.
Bombus ruderatus is part of the order Hymenoptera and the family Apidae. B. ruderatus is in the genus Bombus and is one of 239 species of bumblebees, with 23 of those existing in Britain alone. B. ruderatus is part of the subgenus Megabombus, along with Bombus hortorum. B. ruderatus is most closely related to B. hortorum.
The body lengths of B. ruderatus reach about 22 mm (0.87 in) in queens, 16 mm (0.63 in) in workers... Wikipedia →

Rare
Under 5% of wildlife watchers report a Large Garden Bumble Bee sighting in Lisbon on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 441 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March and May
In those months about 10% of wildlife watchers report a Large Garden Bumble Bee in Lisbon on a given day, against under 5% in April and June–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Large Garden Bumble 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.
2nd of 2
Of the 2 cities where we can rate Large Garden Bumble Bee sightings, Lisbon ranks 2nd at under 5%. The best odds are in Barcelona (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Garden Bumble Bee is recorded against all the insects logged in Lisbon (17 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.
