Do leafhoppers go through complete metamorphosis?

What does leafhoppers do to plants?
Leafhopper damage is characterized by light-colored speckling on plant leaves caused by the leafhoppers sucking sap and plant juices from within the plant tissue. Left unchecked, this gradual feeding reduces the plant’s vigor over time, browning the leaves.
