jumping plant louse

any member of the approximately 2,000 species of the insect family Psyllidae (order Homoptera). The jumping plant louse is about the size of a pinhead. Its head, long antennae and legs, and transparent wings resemble, on a reduced scale, the features of the cicada. Eggs are deposited on leaves or twigs of the host plant; the nymphs, flattened and broadly ovate, usually feed clustered together. Some species are covered with wax; others produce galls on the host plant.
