The acorn weevil's most striking feature is its long snout, called a rostrum.
The female uses her longer rostrum to bore into the centre of an acorn where she lays her egg. The larva feeds on the acorn, eventually tunnelling out as an adult.
Acorn weevils live in oak woodland. They are quite common, particularly in the south of Britain. You may also find them on individual oak trees in hedgerows, parks and gardens.
