Adrian states that bees find floral sources only by odor, and that they go upwind to find them. But it occurred to me that there me be another reason why bees go upwind rather than downwind. Bees may have learned that going downwind is much riskier than flying upwind. If you go upwind light you can sail downwind heavy. If you fly downwind light, it will be much harder to beat your way back fully loaded, especially of the wind increases. (Similarly, I have a rule never to drive downhill in unfamiliar terrain -- it's an invitation to get stuck. You can usually back down from a muddy hill but if you slide down you may never get back up.) But to credit bees with such insight would be to grant them more capabilities than some people are willing to do. On the other hand, it could just be an adaptive thing. Bees that fly upwind to nectar sources may have had an evolutionary edge. -- Peter Borst <[log in to unmask]>
