These bugs are also called billbugs and snout beetles and there are at least 40 000 species making them the largest beetle family. The mouthparts of adult weevils are at the tip of a long snout used to bore into fruits, seeds, and other plant parts. The larvae are legless and feed inside fruits and nuts or are borers. Many weevils are serious crop pests. Adults and larvae cause great damage by eating seed pods. Most weevils are brown or grey, but some tropical species are brightly coloured.
