Leafhopper → The word is formed from "leaf" (from Old English "leáf", meaning the foliage of a plant) and "hopper" (from Middle English "hoppen", meaning to leap or jump). A leafhopper is an insect that jumps or hops among leaves.
Think of a creature that 'jumps' ('hopper') around on 'leaves' — that's why a leafhopper is an insect that hops on leaves.
