Busy bees

bombus1.jpgI like bees. Especially the big furry bumble bees. Here in Australia, the bumble bee is a non-native accidental introduction to Tasmania. There is talk of introducing them to the mainland, on the grounds that buzz pollination can increase agricultural yields. Have we learned nothing from the disastrous introduction of non-native species? How hard can it be to rig up some kind of vibrating wire? Or employ summer labourers with paintbrushes?
Anyway, I enjoyed this Guardian article, which tells us that bumble bees forage over a much greater range than supposed – up to almost 13 km. Or as the Guardian would have it, 8 miles. Note to science editor: science = SI base units. Coincidentally, that’s about the maximum distance that a player covers in an AFL game.
