The Indian Meal Moth life cycle is described as complete metamorphosis; egg, larval (caterpillar), pupal and adult stage. The adult is a small moth, about 3/8 inches long with a wingspan of about 5/8 inches. The wing color is generally gray but the rear half of the wing is rusty brown or nearly bronze. This wing pattern allows Indianmeal moths to be easily distinguished from other household moths. The larval stage is usually cream colored, sometimes with yellowish-green or pinkish shades, and has a dark brown head. Larvae may be seen as they wander in search of a place to pupate, or pass through the pupal stage. Often, the larval and pupal stages are seen on walls and where the wall and ceiling meet.
