The early bumblebee or early-nesting bumblebee (Bombus pratorum) is a small bumblebee with a wide distribution in most of Europe and parts of Asia. It is very commonly found in the UK and emerges to begin its colony cycle as soon as February which is earlier than most other species, hence its common name. There is even some evidence that the early bumblebee may be able to go through two colony cycles in a year. Like other bumblebees, Bombus pratorum lives in colonies with queen and worker castes. Bombus pratorum queens use aggressive behavior rather than pheromones to maintain dominance over the workers.
The queen is black with a yellow collar (the band around the front of the thorax), another yellow band on the first tergite (abdominal segment), and red colouration on the tail (terga 5 and 6). The male has a wider yellow collar, yellow colouration on both terga 1 and 2, and a red tail, also. The workers are similar to the queen, but often with less yellow colouration; usually the abdominal, yellow band is more or less missing.

With luck
About 10% of wildlife watchers report an Early Bumble Bee sighting in Brussels on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 337 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report an Early Bumble Bee in Brussels on a given day, against under 5% in July–September and November–January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Early Bumble 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.
11th of 26
Of the 26 cities where we can rate Early Bumble Bee sightings, Brussels ranks 11th at about 10%. The best odds are in Birmingham (United Kingdom, about 30%), Liverpool (United Kingdom, about 30%) and Manchester (United Kingdom, about 20%).
Same genus: Bombus
The closest relatives of the Early Bumble Bee that you can see in Brussels (genus Bombus, Bumble Bees) are Common Carder Bumble Bee (about 20%), Tree Bumble Bee (about 10%) and Red-Tailed Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Early Bumble Bee is recorded against all the insects logged in Brussels (44 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.
