Scientists have discovered what they believe is the first example of interacting gears in young planthopper insects, Issus coleoptratus. The gears are on the upper portion of the insect's rear legs and help ensure the legs work in unison when the insect jumps. These gears are lost as the animal ages and are thus rather like training gears.
Dr. Malcom Burrows (Emeritus Professor of Neurobiology at the University of Cambridge, UK) was quoted in Live Science as saying "To the best of my knowledge, it's the first demonstration of functioning gears in any animal."
Here is a video of the gears in action:

Great article. Cockroaches,Firefly and other insects offer great ideas for adoption. Bio mimicking at its best.
You have a beuatiful blog, just bookmarked it.
Yes, I wonder which HOX clusters made that?
Really cool...it says in the LA times that researchers weren't even looking for these gears when they came across them. Now that scientists are aware of these gears they can look for them in other organisms.
