Appearance
Like all planthoppers, the nymphs of this insect have a small, gear-like structure on the base of each of their hind legs. These gears have teeth that intermesh, keeping the legs synchronized when the insect jumps, preventing it from spiraling. This is the first planthopper species in which the function of these gears was described, though their existence had been known for decades. The insects shed this gear before moulting into adults.
Behavior
There is only one generation per year. It is unable to fly, unlike most members of its family. It feeds on the phloem of different trees, such as lime trees, oaks, maples, birches, elms and hazels.References:
