Pests in Gardens and Landscapes

Eucalyptus snout beetle—Gonipterus scutellatus

Adult eucalyptus snout beetles are rust-colored weevils. Their mouth parts are elongated into a short snout and they have clubbed antennae. Larvae are yellowish green in color with a dark stripe and black spots on each side.

Life cycle


Mature larvae and adult weevils feed only on eucalyptus foliage, the leaves appearing notched, ragged, or scalloped. Young larvae feed only within leaf veins, leaving the leaf epidermis alone.


Eucalyptus snout beetle is controlled biologically by Anaphes nitens, an introduced parasitic wasp. No further control is necessary.
