Pest Description

Look for round white eggs in groups of 5 to 200 on the upper surface of the upper leaves. The eggs gradually become darker in coloration, hatching in five to seven days. Newly hatched larvae are pale with light-brown stripes running lengthwise down the back. This insect is an occasional problem in western Kansas.
