Image of GRANARY WEEVIL Sitophilus granarius 
Length: Approximately 4 mm 
Small, moderately polished, blackish or chestnut-brown beetle. The head extends into a long slender snout with a pair of stout mandibles or jaws at the end. There are no 
wings under the wing covers, and the thorax is well marked with longitudinal punctures, two characteristics that 
distinguish this insect from the closely related rice weevil with which it is often found. 
Prefers wheat and rye, but also feeds on corn, barley, millet, rice, and buckwheat, less on oats; the weevil occasionally eats flour, whole meal, or pasta.
