What does curculio mean?
Curculio is a noun referring to a weevil — a small beetle with a distinctive elongated snout — particularly those of the genus Curculio, whose larvae tunnel into nuts and stone fruits such as acorns, plums, and apples. The name derives directly from the Latin word for weevil, making it one of the older scientific terms still in common horticultural use. In practical terms, the word matters most to growers and entomologists: the plum curculio of North America is a notorious orchard pest that scars and destroys developing fruit, and 'curculio damage' is a familiar phrase in agricultural literature. More broadly, the term connects to Curculionidae, the enormous weevil family that ranks among the largest groups of animals on Earth. Though rarely heard outside specialist contexts, curculio carries a precise, authoritative tone and is indispensable in discussions of fruit-growing, pest control, and beetle taxonomy.
nounA weevil, especially any of several small beetles of the genus Curculio whose larvae infest nuts and fruits such as acorns, plums, and apples; the term is also used more broadly for the large weevil family Curculionidae.
- A weevil of the genus Curculio, especially one whose larvae bore into nuts or stone fruits such as plums and apples.
- More broadly, any member of the weevil family Curculionidae.
"The orchard lost much of its plum crop to the voracious curculio."
"Growers monitor for plum curculio as soon as the fruit begins to set."
"An individual curculio can ruin dozens of developing acorns in a single season."
In English, curculio takes the regular plural curculios; the Latin-style plural curculiones appears occasionally in strictly taxonomic writing but is rare.
"Several curculios emerged from the stored acorns."
The word 'curculio' comes straight from ancient Rome — Latin speakers were complaining about this nut-boring weevil two thousand years before it plagued American orchards.

Etymology of curculio
Curculio was borrowed in the early modern period directly from Latin curculio, meaning 'weevil' or 'grainworm', a diminutive-form word used by classical Roman writers. It entered English chiefly through natural history and entomological writing, where it became the formal basis for the weevil genus Curculio established in early scientific classification. The related adjective curculionid reflects the same Latin stem via modern taxonomic naming of the family Curculionidae.

How curculio is actually used
Curculio is a technical term used chiefly in entomology and agriculture rather than everyday speech. In North America it most often refers specifically to the plum curculio (Conotrachelus nenuphar), a serious orchard pest, while in broader taxonomic use it names the genus and its family, Curculionidae — the largest known animal family.
