It's called "Weevil" a beetle species of the family Curculionidae, the largest and most diverse of the superfamily Curculionoidea, Coleoptera order. The most numerous family of Curculionoidae.
It is one of the most diverse animal families and species-rich. The family of weevils includes more than 100 subfamilies, are known to more than 40,000 species worldwide.
Phytophagous habits are herbivores (feed on plant foods) and their relatives the leaf beetles.
The adult weevil is usually dull colored. Its size depending on the species can vary from 1.5 to 35 mm long (excluding the face). You can find smaller species or larger. The species vary greatly in color and in form and structure.
They are characterized by their chewing mouthparts at the tip of a proboscis that can be relatively massive or long and narrow, depending on the species.
Antennas, mazudo end, are sheltered in a row along the proboscis.
Its oval body is covered with a coat rough and tough and has a single medial suture at the bottom of the head. The size is generally small when compared to other beetles.
The weevils are usually covered with scales or hairs, but can be virtually naked.
Most species fly but in some environments, dominated by species that do not fly.
The beetles undergo complete metamorphosis. From the egg comes a larva. The larvae are white, semicircular, fleshy, with vestigial legs, powerful jaws and rudimentary eyes, feed only on plants, causing extensive damage to crops. The larva grows to pupate in a kind of capsule. After a time capsule of an adult emerges. Adults often hibernate for most of the winter. There are adult males and females. After mating, females lay eggs. In some cases lay eggs in the field, and in other cases have in the grain mass.
Each female lays about 300 eggs. Also, the life cycle is short and there may be two or three generations in one year. Thus, when the year began with a single pair of weevils at the end of the year could be more than 5 million! And in hot places, proliferate.
