Caption: Acorn Weevil (Curculio nucum). One of the most interesting facts about the acorn weevil is their egg laying process. The adults mate during the early summer months, high in the oak trees. Once the females are fertilized they will deposit their eggs in tiny chambers in the new soft-shelled acorns that have been drilled with their amazing snout. When the eggs are deposited, the female will close the opening with a fecal plug to protect the eggs. The plug dries, turning white in color, keeping the eggs and larvae safe from predators. When the eggs hatch the larvae feed on the soft insides of the acorn until the nut drops from the tree. Once the larvae have matured they will drill an exit hole out of the acorn and burrow in the soil near where the acorn has fallen. Interestingly, most larvae remain in the soil for up to three years before they pupate during the spring. New adult acorn weevils appear in early summer, crawling up the base of the oak tree to begin feeding and mating.
