Curculionidae is the family of the "true" weevils (or snout beetles). With over 60,000 species described worldwide, it is the largest of the beetle families.
They are recognized by their distinctive long snout and geniculate antennae with small clubs; beyond that curculionids have considerable diversity of form and size, with adult lengths ranging from 1 mm to 40 mm.
Weevils are almost entirely plant feeders, and most species are associated with a narrow range of hosts, in many cases only living on a single species.
With so many species to classify and over 400 genera, the taxonomy of this family is quite complicated, and authors disagree on the number and placement of various subfamilies, tribes, and subtribes.
The word weevil has been made famous by the Boll Weevil, which lays its eggs and eats inside cotton bolls, killing the plant.
