Acorn weevil

Curculio glandium

''Curculio glandium'' is a species of carpophagus weevil, known as the acorn weevil. It is native to eastern North America. It eats by a rostrum, an elongated snout, that is used for piercing. Male/Female differentiation can be determined using the rostrum as female's are longer. The larvae are short, and cylindrical in shape, and move by means of ridges on the underside of the body. Adults can reach a length of 4 to 8 mm.

''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''.''
