On a recent trip to the UK the bumblebees were prolific in the lavender flowers. They were busy all day and even into the early summer evening. It was lovely to watch them, especially as many of the species are in decline and two have actually become extinct.
I always remember studying them in school when I was doing my A levels and the teacher telling us they were aerodynamically unable to fly. This always puzzled me, but I now read that this was a misconception of the 1930s and in 2005 it was shown through high speed photography, that the way they flapped their wings was different to the way previously understood. I do love science!
Bumblebees are mainly under threat because of changes to the countryside in the UK. Changes in agricultural techniques have meant that there are far fewer wildflowers in the landscape than there used to be, meaning that many of our bumblebee species are struggling to survive.
