The Curculionidae comprise the family of the "true" weevils (or "snout beetles"). It is one the largest animal families, with 5,489 genera and 86,100  species described worldwide.

It also includes the bark beetles as subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae.
