description Bombus pratorum Overview
Bombus pratorum, commonly known as the early bumblebee, is a widespread bumblebee species found throughout Europe and parts of Asia. It is characterized by its relatively small size and distinctive yellow, black, and orange coloration. The species earns its common name from its early spring emergence, with queens typically appearing before many other bumblebee species. B.
pratorum colonies have shorter annual cycles than most other bumblebees, often completing their life cycle by mid-summer.
help Bombus pratorum FAQ
How do you identify Bombus pratorum?
The early bumble bee is usually black with a yellow band near the front of the thorax and a reddish-orange tail. Queens and many workers also show a second yellow band on the first abdominal segment, although markings can vary.
Why is Bombus pratorum called the early bumble bee?
Its queens can emerge from hibernation as early as February in milder parts of Europe. Colonies develop quickly, with workers appearing roughly six weeks after a nest is founded.
Where does Bombus pratorum build its nest?
It uses varied cavities, including abandoned rodent burrows, bird boxes, compost heaps, and spaces in buildings. This flexibility distinguishes it from bumble bees that nest almost exclusively below ground.
Which cuckoo bumble bee parasitizes Bombus pratorum?
Bombus sylvestris, commonly called the forest cuckoo bumble bee, is its principal social parasite. A female B. sylvestris enters a B. pratorum nest and uses the resident workers to raise her own offspring.
