Frequently Asked Questions

Behavior, Diet & Habits

Understanding Angoumois Grain Moths

Appearance

  • Size: They are small in size with a front wingspan about 3/16 inches. Full-grown larvae are about 1/8 inches long.

  • Color: They are yellowish in color. Full-grown larvae are usually yellowish-white with a yellowish-brown head.

  • Characteristics: A very important distinguishing characteristic is a narrow projection that extends from the tip of their hind wing.

Diet

Adult moths do not feed on grains. Larvae feed on:

  • Corn kernels

  • Grains

  • Seeds

  • Wheat

Habitat

When found in homes, common places for these pests include:

  • Popcorn

  • Decorative ears of corn.

  • Decorative boxes of seeds.

Life Cycle

The complete life cycle (egg to adult) can be completed in as little time as five weeks.

  1. Egg: Eggs are laid on or near grain either in the field or during storage.

  2. Larval: Larvae then penetrate the kernel and continue to feed until mature, while creating and enlarging a cavity within the kernel.

  3. Pupal: When mature, the larvae eats a channel to the outside of the seed and spins a silken cocoon.

  4. Adult: They then pupate within the kernel and emerge as an adult moth.
