acorn weevils, nut weevils
Curculio is a genus of weevils in the family Curculionidae, commonly known as acorn weevils or nut weevils. Females use their elongated rostrum to bore holes in developing nuts of oak, hickory, and other trees to deposit eggs. Larvae develop inside the seeds, feeding on the nutritious kernel, then emerge in autumn to pupate in soil. The genus has been extensively studied due to its economic impact on nut production and its remarkable morphological adaptations for seed predation.
