A first instar European corn borer will scrape the upper tissue from a corn leaf leaving a thin membrane or "window pane" in the leaf. Note the characteristic black head of this corn pest.

Setae (hairs) on the dorsal side of European corn borer larvae are encircled by a darker-colored “halo� or ring. This is a distinguishing characteristic with this insect in separating it from other corn attacking caterpillars.

Spray planes can be used to apply insecticides to corn to help control potentially-damaging populations of European corn borers.

The adult moth of the southwestern corn borer.

The summer stages of the southwestern corn borer have a light reddish brown head and 10 dark spots on each segment in the middle of the body.

The overwintering stage of the southwestern corn borer is milky white in color with no distinguishable spots.

Southwestern corn borer eggs have three, narrow red bands. The eggs are laid overlapping each other like fish scales.

After the whorl is pulled, early-stage larvae can be counted as the leaves are unrolled.
