Pterocolinae is a of weevils commonly known as thief weevils. Members of this group are kleptoparasites that exploit the nest-building of other insects, particularly leaf-rolling weevils. The best-documented , Pterocolus ovatus, occurs in Florida where it parasitizes the nests of Homoeolabus analis. These weevils have minimal impact on their plants and are primarily of ecological interest due to their parasitic life strategy.
