About

The acorn weevil is usually found on or around oak trees. Females use their long snout (called a rostrum) to make a hole in a developing acorn. They then lay eggs inside the acorn – typically just one or two eggs per acorn. The larvae live inside the acorn, feeding on it. When the acorn has fallen to the floor, they chew their way out and bury themselves in the ground. They'll spend at least three winters underground, before eventually emerging as an adult in spring.
