Bombus terrestris

Bombus terrestris (Buff-tailed Bumblebee)

Status: introduced pest.

When I first saw bumblebees in Tasmania I was chuffed, as they're not on the mainland. Like so many things ecological, I was ignorant of the bigger picture.

Sometimes I'm just totally stumped by the level of arrogance and stupidity humans are capable of. Bumblebees are were/are on the "dangerous pest" list to be not allowed into Australia, yet someone decided they knew better.

Apparently there have been two queen/hives brought into Tasmania illegally, and they've taken hold. They're a real problem because they:
  1. complete with native bees
  2. consume copious amounts of nectar, putting pressure on all sorts of species (apparently some parrots are very vulnerable)
  3. are more adapted to pollenating introduced plant species than natives - to they spread weeds better than our native bees
  4. can cut through flowers where they find difficult to reach the nectar (think natives) - so they don't pollinate them at all

Simply put this is another in the long list of ecological stuff ups that was completely avoidable. Fortunately because there are only two hives, the inbreeding has slowed them - and will hopefully make them susceptible to eradication should someone persue it.
