Many weevils of this group are commonly known as flower weevils or acorn and nut weevils, after a food commonly eaten by Curculioninae larvae and imagines — the reproductive organs of plants.

Systematics

This large subfamily is divided into around 30 tribes. Delimitation of the Curculioninae is fairly robust considering its enormous size; there is some dispute, however, in their exact boundary with the Molytinae. The Phrynixini and Trypetidini are also included in the Curculioninae by some authors, but more often they are considered Molytinae; conversely, the Itini are usually placed in the Curculioninae but sometimes in the Molytinae, which are also expanded by certain authors to include, among others, the whole Cryptorhynchinae. These, as well as the Ceutorhynchinae, are sometimes included in the Curculioninae as additional tribes Cryptorhynchini and Ceutorhynchini. And some genera while almost certainly Curculioninae, are too unusual and/or ancient to be easily assigned to a specific tribe.

Features used to distinguish some of the tribes are:

Pygidium exposed Acalyptini[2]
Ceutorhynchini
Foreleg femora with large triangular tooth Camarotini[3]
Tarsi with one claw (not two) Cryptoplini (including Haplonychini)
horizontal
)
some Curculionini
Prothorax with lateral keels Derelomini[2]
Prothorax narrowed at base (
ant mimic
)
Hindleg femora enlarged Eugnomini (with triangular tooth)
Rhamphini (swollen for jumping)
Tarsal claws fused at base Smicronychini[3]
posterior to coxae: Cryptorhynchinae
)
Storeini
