Title: How do bumblebees fly?
Post by: Corey Wolffs on 08/07/2008 12:34:15

Corey Wolffs asked the Naked Scientists:

I am an art student in Oakland, California and I just wanted to say thank you for such a fantastic show.

I wanted to ask about bees. One day while I was sitting outside, I saw a large bumble bee crawling about while madly beating its wings. I then remembered someone saying that a bee's wingspan was far too small for its massive body and that bee flight was scientifically and aerodynamically impossible. I was wondering if  you at the Naked Scientist could shed some light on this bee-nigma. Thank you.

What do you think?

I believe it has something to do with the bee clapping its wings behind its back which creates extra lift. I'm not sure how that works.

It's a rural myth!

Corey,
Was the time of day morning?  Was the temperature cool?  It sounds like the bee might have been warming up its flight muscles by vibrating the wings.

The main reason is that you can't just scale aerodynamics. You can't be subjective about such matters. For a bee, the air is very 'thick' compared with how it is on our scale.  Insects will fall at a very low terminal velocity because their weight is so small. For a bee in air, it's almost like it is for humans swimming in water - despite the fact that insects are still heavier than air.
