lephant weevil ( Orthorhinus cylindrirostris ) and vine weevil ( Orthorhinus klugi ) Elephant weevil and vine weevil are native species that breed in many native trees, especially eucalypts. The adult elephant weevil may vary in length from 8 to 20 mm, and the vine weevil is about 7 mm long. The weevil body is densely covered with scales that may vary from grey to black. The larva or grub is soft, fleshy, creamy yellow and legless, and reaches a length of nearly 20 mm. The pupa is soft and white, with light brown wing buds. Most beetles emerge during September and October, and lay eggs in holes drilled at the base of the vine with the proboscis. The larvae tunnel for about 10 months, the pupal stage lasts for two to three weeks, and the adults emerge a year after the eggs were laid. If chemical control is required use a registered insecticide
