Leafhoppers may sometimes be confused with aphids or lygus bugs. Look for leafhoppers or their
cast skins on the undersides of affected leaves. Look at their actions; they are faster than aphids
and run sideways and jump. Lygus bug nymphs are light green and also move much faster than aphids.
They can be identified by their red-tipped antennae. Aphids can be distinguished by two tubelike
structures, called cornicles, protruding from the hind end.
