Issus coleoptratus is a species of planthopper belonging to the family Issidae.

[1] This common species can be found in the western Palearctic realm, in the Near East, and in North Africa.

[4] Like all planthoppers,[5] the nymphs of this insect have a small, gear-like structure on the base of each of their hind legs.

[6] These gear-like structures 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 gear-like structures was carefully described,[6] though their existence had been known for decades.
