Spring is very much upon us.

First up today, a new one for me: a planthopper nymph, Issus coleoptratus (Echte Käferzikade in 🇩🇪).

Nymphs of this species were the first insects found to have working gears – they're at the base of the hind legs & keep things in sync when they jump ⚙️

They lose them though when they moult into adults 🤷‍♂️

This Insect Has The Only Mechanical Gears Ever Found in Nature

The small hopping insect Issus coleoptratus uses toothed gears on its joints to precisely synchronize the kicks of its hind legs as it jumps forward
