Nymphs of the planthopper have actual gear-like teeth on their hind legs. When jumping with 400G in 2 milliseconds, the gears synchronize both legs within 30 microseconds. Adults lose the gears—damaged ones can't be replaced—and switch to friction instead.

Zebra stripes defend against blood-sucking insects like tsetse flies. In experiments, flies couldn't land on striped surfaces — they crashed or flew past without slowing down. Even regular horses wearing striped coats repelled flies.
