Curculio glandium
Another very strange looking insect, the Acorn Weevil can be found in woodland areas where Oaks grow. The unusually large rostrum is used to bore a hole into the wall of the developing acorn, into which an egg is laid. The hole then heals up as the acorn develops and the larva develops inside. When full grown, the larva burrows out and pupate in the soil. A small hole found in the side of any acorn, may possibly be attributed to this interesting weevil. This is quite a distinctive weevil to identify, the one pictured being about 7mm in length and coloured a rich chestnut. It was one of two found and photographed in Sherwood Forest during early May 2006.
