Curculio glandium is a species of carpophagus weevil, known as the acorn weevil.
It is native to Europe and despite indications it occurs in eastern North America this is based on an erroneous identification and refers to another species of Curculio.
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.
