Gonipterus scutellatus Gyllenhal, 1833 - (eucalypt snout beetle)

This weevil is an important pest of eucalypts, native to Australia. It has been accidentally introduced into various regions including Asia, Africa, southern Europe (first record in 1976 in Italy) and the Americas (in the 1990s).

The slug-like larvae cause the main damage, feeding on the leaf surface and leaving characteristic tracks. The adults damage the leaf edges. Outbreaks can defoliate trees. The egg parasitoid Anaphes nitens has been successfully used as a biological control agent.
