Gears in the garden

Issus coleoptratus nymph

Not a new photo – taken last May – but great to hear that Issus coleoptratus (specifically the nymph, shown here) has been found to use a system of meshed cogs to synchronise its jumping legs, the first time that a gear-type mechanism has been observed in nature. Here’s a link to the story.

It’s not really surprising that evolution has come up with solutions to problems like the speed that signals travel along nerves, but the fact that we have only just discovered it does tell us that there’s a lot more to be discovered!
