Field Guide - Potato Leafhopper
The adult is a pale green, somewhat wedge shaped, and about 1/4″ in length. The adult has distinctive white spots on the head and pronotum. This is a very active insect. Many times, when it moves, it will move sideways much the way a crab will move.
The nymph will appear almost a neon green.
