  • Like the honeybee, bumblebees are social bees. They live in colonies with a queen, many female workers, and some males.
  • Ireland has 20 native bumblebee species. Of these, 6 species are cuckoo bumblebees. These cuckoo species don’t make their own nests, but instead lay their eggs in the nest of a true bumblebee who will inadvertently bring up their young.
  • Clover is an important forage crop in Ireland and is dependent on bumblebees for pollination. The value of clover pollination in Ireland is estimated at 29 million per annum.
  • As with all bees, only the females can sting! Female bumblebees can sting more than once.
  • Four of Ireland’s bumblebees are endangered and 2 are vulnerable. The Great yellow bumblebee is on the verge of extinction from Ireland.
  • Bumblebees are more primitive and don’t make honey like honeybees. Instead they store a little bit of nectar in wax nectar pots in their nests for emergencies. This means that a bumblebee colony is never more than a few days away from starvation, making Ireland and its climate a challenging place to live!
  • Using DNA extracted from a tiny portion of bumblebees legs, researchers identified a new Irish bumblebee species in 2007. It is called the Cryptic bumblebee, Bombus cryptarum.
  • Bumblebees can travel up to 5km to feed but commonly forage within 1km of their nest.
  • Bumblebees have very powerful wing muscles. They have evolved a special adaptation that allows them to decouple these muscles from the wing. This allows them to use the wing muscles to generate heat and then reattach them before flying off.
