Synonyms and other taxonomic changes
Broken down into 4 major groups. The oldest lineages (the paraphyletic "Brachycerinae", treated here as a family) are monocot specialists and have a primitive aedeagus. Dryophthorinae and Platypodinae are closely related and share some larval similarities. Bagoinae forms its own small lineage sister to the remaining subfamilies. The remaining groups feed mostly on dicots and have the more advanced aedeagal morphology. Their phylogeny and classification are still uncertain, but two major clades can be recognized, which correspond to endophytic vs ectophytic larval ecology. The latter includes Entiminae, Hyperinae, Gonipterinae, and Cyclominae. All the others are in the endophytic clade, where many currently recognized subfamilies appear to be para- or polyphyletic.(1)
Explanation of Names
Curculionidae Latreille 1802
weevil: from Old English wifel, akin to German Wiebel and Lithuanian vabalas 'beetle'; from Indo-European root *webh- 'to weave, move quickly' (Online Etymology Dictionary)
Arguably, the largest animal family with more than 50,000 species in ~4600 genera worldwide(2) and 2,500 spp. in ~480 genera of 19 subfamilies in our area (Staphylinidae and/or Ichneumonidae may turn out more speciose.)

1-35 mm (usually 5-15 mm)
most have a well-developed downward-curved snout (rostrum); antennae elbowed, clubbed, and the first segment often fits into a groove in the side of the snout
Good old keys, still useful mutatis mutandis, can be found in(3)
Most are sexually dimorphic with the female rostrum longer, finer, and the position of the antennae more basal than males.
throughout the world
most larvae and adults occur and feed on all parts of plants, and many species are important pests because they chew holes in fruits, nuts, and other parts of cultivated plants (see, e.g.,(4))
Adults often play dead when disturbed (by lying motionless on their back)

Members of many non-weevil families also have rostrate heads, e.g.:
