Field Crop Insects - Joanne Whalen, Extension IPM Specialist . Cereal leaf beetle eggs can be easily found in most wheat fields.
Eggs are elliptical in shape and are yellow to burnt orangish-yellow in color.
Although eggs can be found in most fields, adults prefer to lay eggs in late planted fields and in thinner stands. Larvae will appear slug-like in shape and resemble small Colorado potato beetle larvae except for the color. Scouting should begin by mid-April to determine if egg hatch has begun. As soon as the weather turns warmer, you should begin to see egg hatch. In warmer weather, damage can occur in as little as five days.
