Behavior
''Curculio glandium'' eggs are deposited in acorns by the adult weevil chewing channels into the fruit. The eggs are then released using an ovipositor, a long, narrow organ featured in female weevils. These do not reach the acorn's embryo and are healed by the plant, sealing the holes and protecting the eggs from parasites. Upon hatching, either one or two larvae consume the fruit. While they may eat the entirety of the acorn, the larvae typically do not consume the embryo itself''.'' ''Curculio glandium'' live throughout winter in the larval stage. The larvae are freeze avoidant, preventing their internal body fluids from freezing during the winter''.''References:
