Adults are small brown slender beetles, about 3 mm in length. Adults are very similar morphologically to sawtoothed grain beetle. May be separated from sawtoothed grain beetles based on the width of the temple (wider in sawtoothed grain beetle). Larvae are white to pale yellow and flattened.
Damage: Damage is generalized and not necessarily identifiable as coming from this particular species. Both adults and larvae feed readily causing damage. In dwellings, they are normally carried into the house with food. In apartment buildings, they sometimes migrate, spreading from unit to unit and become a chronic pest.
