Apple sucker

Cacopsylla mali

Adult resembles a miniature cicada, greenish yellow to yellow in color but sometimes containing reds or browns, with eyes pale green to reddish brown, and long slender antennae; wings are transparent and iridescent (A). The nymph is pale yellowish green with green eyes, body short and broad with a flattened appearance, and rounded posteriorly, with prominent wing pads (B, arrow).

Attacks apple. Motile stages are "flush feeders" that suck sap from newer, tender growth, and secrete excess fluid as honeydew. This collects on leaves and fruits, provides a good medium for sooty mold growth, and can kill leaf tissue. Excessive feeding and injection of toxic saliva can cause wilting and premature leaf drop.
