Description and Damage: Adults are straw-colored, shield-shaped, and 1 /2 inch long. The adult has for-ward projecting points on each shoulder. Females deposit 10 to 50 light green, short, cylindrical eggs in a two-row cluster. Eggs hatch after about 5 days. Nymphs require 15 to 28 days to become adults.

Stink bugs feed mainly on kernels and cause the most damage during early kernel development.
