Acorn Weevil

It is a medium-sized beetle, with an especially elongated snout, characteristic of the Curculionini tribe of the weevil family (Curculionidae). The most striking feature of the acorn weevil is its elongated snout, known as a 'rostrum', which is longer in females than males. Adults have a brownish and patterned body. The larvae are short, and cylindrical in shape, and move by means of ridges on the underside of the body. This species is often confused with another commonly occurring weevil of the same genera – the gland weevil, Curculio glandium, which lives on hazelnuts. Despite overall similarity, the weevils differ in some morphological details. Curculio nucum has broader segments of flagellum and the segment sare covered with standing-off setea which in C. gladium are adjacent.
