Wheat Weevil
Commonly called the granary weevil, the wheat weevil is best known for its destructive potential in agricultural communities. Using their plump mandibles, females puncture grain kernels in order to deposit eggs. Eggs hatch into larvae, whose nutrition is secured by the content of the kernels. Pupae emerge within five weeks and mature within five months. Since they are unable to fly, granary weevils prefer stored grains over those found in fields.
Granary weevils are typically brown in color and measure up to five millimeters in length. They feature highly-pronounced pitted patterns on their heads. While they are equipped with wings, wheat weevils are incapable of flight. They are similar in appearance to rice weevils, although their wings exhibit no spotting.
