Scientific Name: Gonipterus scutellatus

Common Name(s): Eucalyptus weevil

Other Names: eucalyptus snout beetle, gum tree weevil.

Class: Insecta

Order: Coleoptera

Family: Curculionidae (true weevils)

Genus: Gonipterus

Species: scutellatus

Distribution: Australia where suitable host speices of Eucalypts occur. Has moved to many overseas countries where eucalypts have been planted, including China,

Habitat: Feeds on Eucalypts . E. camaldulensis, E. globulus, E. maidenii, E. punctata, E. robusta, E. smithii, E. viminalis.

Field Notes: Looks very much like a gum nut, as does the related G. gibberus. Difficult to see when in gum nut clusters. Is a pest in overseas plantations where no predators exist, can even kill trees. It could be used as a biological control agent for these countries, when the weed potential of eucalyptus becomes more apparent. Lif cycle is as little as 11 weeks, eggs are laid in the hundreds on leaves.
