Elephant Weevil - UPDATE 14/10/2008

Orthorhinus cylindrirostris, is commonly known as the Elephant Weevil. Elephant Weevils and associated damage have been seen. These are rare in McLaren Vale, but in other regions like the Hunter Valley in NSW, they are a major pest.
Elephant Weevil.
A hollowed out vine trunk.
Look out for any weak vine arms with hollowed out wood. The female elephant weevil bores a hole into the trunk or arm of the vine. Into this hole she lays an egg. On hatching the young weevil larva begins to feed on the wood, boring downwards eating as it goes. When fully grown, the larvae makes its way back up the tunnel it has made until it reaches the point close to where it hatched, and here it pupates.
