Weevils

A weevil is any beetle from the Curculionidae superfamily. They are usually small, less than 6 mm (1/4 inch), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). The rice weevil and granary weevil are pests of stored grain and seeds. They develop inside whole grain kernels as small, white, wrinkled, grub-like larvae. There is generally no external evidence that the larvae have been eating and growing inside the seed until after about one month when the adult weevil chews through the seed coat and emerges. The adult weevils are 1/8th inch long and have slender, hard-shelled bodies that appear pitted or scarred with tiny holes. They are brown to reddish brown in color. The rice weevil has four faint yellowish spots on the back of the abdomen. The granary weevil is uniformly colored with no spots. Source: Wikipedia.com
