The weevil is a small insect that usually occupy the insides of grains or fruits. They belong to the family Curculionidae and have over 60,000 species.
HOW TO IDENTIFY WEEVILS
They are also known as ‘snout beetles’ because they have a snout with the mouth at its end. This snout is the reason for their success. It is used to penetrate into grains and fruits, and also to burrow holes in which to lay eggs. Different species differ in the appearance of their snout, some have rounded and some have tubular snouts.
Sometimes, their snout is even longer than their head. Some species do not have a distinct snout and have a cylindrical body. They are usually found in fields, gardens, and orchards.
Weevils may have an oval or elongated body. Some of them lack wings, but others can fly fairly well such as rice weevils. They range in length from 6mm to 80mm. They have paired antennae. Weevils are usually dark-colored, brown or black, but some species bear strikingly bright colors.
Weevils feed on plant material. Their larvae are very particular in this regard, because they may only eat certain parts of the plant, such as seeds or fruits. The adult larvae have fewer specifications when it comes to food. Weevils may sometimes find their way in your food products or stored grains. Aside from eating them, they also contaminate these food products with their feces and sloughed off skin, thus rendering it inedible. Weevils may act as predators, scavengers or simply herbivores but some have also shown parasitic behavior.
