The Living Forest (413) : Acorn Weevil

The acorn weevil is a beetle that is usually to be found on oak trees in European forests.
The most striking feature of this insect is its elongated snout, known as a 'rostrum'.

Females lay their eggs in acorns.
The long rostrum is used to bore through the thick wall of the nut with jaws located at the tip of the rostrum.

When it has almost reached the centre of the nut, the eggs are inserted in the hole, which subsequently heals up.
The larvae develop inside the acorns, burrowing out when they are fully-grown in order to pupate in the forest floor.

Dutch name : Eikelboorder
German name : Eichelbohrer
Latin name : Curculio glandium

(the insect on the right side is unknown to me)
