Superman, Meet the Super Girls

Dec 23, 2008

You're sitting around discussing the importance of honey bees. The points include: they give us honey, they pollinate agricultural crops, and they serve as an example of a well-organized society.

But wait, there's more.

They scare off plant predators.

"Researchers in Germany discovered that the flapping of bees' wings scared off caterpillars, reducing leaf damage," writes BBC correspondent Richard Black in a Dec. 22 post.

"Many wasp species lay their eggs in caterpillars, and so caterpillars have evolved to avoid them. The sounds of bees' and wasps' wings are similar. Writing in the journal Current Biology, the scientists suggest this is an added bonus of having bees around, as well as the pollination they provide."

That makes sense. The sound of a bee buzzing can prompt a human or animal to leave the vicinity quite rapidly. Why wouldn't a caterpillar do so after "hearing" a buzz? Especially when it can't distinguish the sound of bee wings from wasp wings?

Lead researcher Jürgen Tautz of Wurzburg University says this is an unexpected advantage of why bees are important.

Look at it this way: our little honey bees are super heroes! They deserve to wear an "S" on their thorax.

Actually, they're "Super Girls" as the worker bees are all female. Worker bees are the ones that  gather the nectar and pollinate the plants--and scare off those pesky caterpillars.

Superman, meet the "Super Girls!"
