Bumble Bees shouldn't be able to fly, according to scienctific laws!
The Barbarian said:Both effects are discussed in Steven Vogel's excellent work on biomechanics, Life's Devices". He has a follow-up called Cat's Paws and Catapults that is also quite good.
Inside the bee, there's a small pad of resylin (a biological rubber chemically similar to, but even more efficient than elastin) under each wing hinge. As you hinted, the bee recovers almost all of the energy from the downstroke from the compression and release of resylin.
Hence, the bumblebee flys just fine, thanks to the evolution of efficient materials.
I wonder what these "efficient materials" were that these insects had?
Do we have any evidences of any simpler hymenopterans existing before Bumble bees?
When did bumble Bees first appear and their ancestors disappear?

If you think Reynolds Numbers pose a problem for bumblebees, consider bacteria. For them, motion in water is like swimming in warm tar!
Cat's Paws and Catapults.... Is he the guy that came up with this?
we still have many of those primitive hymenopterans around today.
However, we do have some cousins. Chimps, for example, are also descended from earlier apes that also gave rise to us.
