Quick Summary

Curculio rectus is a species of weevil, a type of beetle belonging to the family Curculionidae. These insects are characterized by their exceptionally long and slender snouts, which in females can be nearly twice the length of their bodies. The snout is equipped with mandibles at its tip, used for chewing holes in nuts to deposit eggs. Specifically, C. rectus and C. baculi are known to feed on acorns. Other species within the Curculioninae subfamily, and the broader Curculio genus, also exhibit similar feeding habits, with some targeting fruits like plums and apples, while others, like Conotrachelus juglandis, feed on nuts.123
