[3] Both this beetle and its larvae feed on the young leaves, buds and shoots of various species of Eucalyptus, causing a slowing of the growth of the tree, a contortion of the twigs and sometimes a dieback of the branches.

The female snout beetle lays batches of about ten eggs enclosed in capsules with hard shells.

This is the case in South Africa, which harbors an undescribed species of eucalyptus-feeding Gonipterus[3] and A. nitens has been introduced to the country to attempt to provide biological control of the pest.

In this case, the snout beetle is found to have three main egg-laying periods, April, July and November.

The April eggs are the most heavily parasitised and it has been found that the larvae of the chalcid wasps are able to diapause in the November eggs, enabling the parasitoid to endure winter conditions that are unsuitable for the survival of the adult wasps.
