Additional comments

Damage can be detected by leaves being distorted, mottled, curled under, and turning brown. Leaves bear characteristic black spots of larval fecal material. Plants become stunted and flowers become discolored. Fruit surfaces become bronze in color. Large populations are particularly common on plants that are water-stressed.

Species identification requires at least a dissecting microscope with 40x magnification. Often, slide mounted specimens are required for verification.
