Cacopsylla pyricola Foerster
Hemiptera: Sternorrhyncha: Psyllidae
Distribution: Widespread and a major pest in most fruit-growing states and provinces in eastern North America.
Adults (A) resemble very small cicadas and can be reddish brown (overwintered generation) or tan to light brown (summer forms). Smaller, wingless nymphs are yellow with red eyes, flat and oval in shape, and develop within a clear honeydew drop (B). Larger "hard shell" nymphs are darker, with black areas interspersed with green or brown coloration (C); these forms have noticeable wing pads and are free-living.
