REDBUD 



Redbud Leafhopper, Erythroneura bistrata McAtee, fig. 43. 

 — This is the most common of several species of leafhoppers that 

 feed in great numbers on the foliage of redbud. With sucking 

 mouthparts, the insects feed on the under sides of the leaves, 

 withdrawing the plant juices and chlorophyll so that the leaves 

 become blanched. The adult, about one-eighth inch long, is 

 marked with red. The nymph, similar in shape but smaller, is 

 whitish. Both forms are active; adults fly up in small clouds 

 when disturbed. This insect has two or three generations a year.
