Most weevils have the ability to fly (including pest species such as the rice weevil), [2] [3] though a significant number are flightless, such as the genus Otiorhynchus, and others can jump. One species of weevil, Austroplatypus incompertus , exhibits eusociality , one of the few insects outside the Hymenoptera and the Isoptera to do so.
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families with 6,800 genera and 83,000 [ 1 ] species described worldwide. They are the sister group to the family Brentidae .

A synthetic version is available which attracts rice weevils, maize weevils and grain weevils. Females produce a pheromone which attracts only males. Its gammaproteobacterial symbiont Candidatus Sodalis pierantonius str. SOPE is able to supply rice weevil with essential vitamins like pantothenic acid, riboflavin, and biotin. [7]
Brentidae, sometimes known as the primitive weevils, is a cosmopolitan family of primarily xylophagous beetles also known as straight-snouted weevils. The concept of this family has been expanded with the inclusion of three groups formerly placed in the Curculionidae ; the subfamilies Apioninae , Cyladinae , and Nanophyinae , as well as the ...
