Occasionally found in New Jersey and Pennsylvania feeding on corn stored on the ear. Damage by this insect is minimal in shelled corn. However, the larval stage of this insect more commonly feeds within kernels of other gains. Grain infested by the angoumois grain moth larvae has an unpleasant smell, and is less attractive for consumption.

Most problems with the angoumois grain moth in corn occur in crib-stored ears, although the infestation may have begun in the field. Corn infested in the field may harbor larvae feeding within corn kernels.

When the newly harvested, infested corn is cribbed, the larvae continue to develop, pupate, and emerge as adults, which in turn deposit eggs on uninfested kernels. Several generations of the insect can be completed during prolonged warm falls, resulting in a large portion of the grain being damaged.

Angoumois grain moth larvae feed on a number of whole kernel grains. Their feeding causes a reduction in grain weight and quality. Heavily infested grain smells bad and is less attractive for consumption. Corn cribs infested with this insect will contain ears with small holes on individual kernels. Ears throughout the crib will be infested. In bins, however, only the top few inches of grain will be infested.

Tineola bisselliella, known as the common clothes moth, webbing clothes moth, or simply clothing moth, is a species of fungus moth (family Tineidae, subfamily Tineinae). It is the type species of its genus Tineola. The larvae (caterpillars) of this moth are considered a serious pest, as they can derive nourishment from clothing – in particular wool, but many other natural fibers – and also, like most related species, from stored foods, such as grains.

Clothing Moths are notorious for feeding on clothing and natural fibers; they have the ability to digest keratin protein in wool and silk. The moths prefer dirty fabric for oviposition and are particularly attracted to carpeting and clothing that contains human sweat or other organic liquids which have been spilled onto them; traces of dirt may provide essential nutrients for larval development. Larvae are attracted to these areas not only for the food but for traces of moisture; they do not require liquid water.

The range of recorded foodstuffs includes cotton, linen, silk and wool fabrics as well as furs. They will eat synthetic fibers if they are blended with wool. Furthermore, they have been found on shed feathers and hair, bran, semolina and flour (possibly preferring wheat flour), biscuits, casein, and insect specimens in museums. In one case, living T. bisselliella caterpillars were found in salt. They had probably accidentally wandered there, as even to such a polyphagous species as this one pure sodium chloride has no nutritional value and is in fact a strong desiccant, but this still attests to their robustness.

Unfavorable temperature and humidity can slow development, but will not always stop it. Both adults and larvae prefer low light conditions. Whereas many other Tineidae are drawn to light, common clothes moths seem to prefer dim or dark areas. If larvae find themselves in a well-lit room, they will try to relocate under furniture or carpet edges.

Handmade rugs are a favorite, because it is easy for the larvae to crawl underneath and do their damage from below. They will also crawl under moldings at the edges of rooms in search of darkened areas where fibrous debris has gathered and which consequently hold good food.
