Eucalyptus snout beetle (Gonipterus platensis) is a leaf-feeding beetle that is a major defoliator of eucalypts, according to the Food and Agriculture Organization of the United Nations. The pest is indigenous to Australia but occurs in many countries throughout the world where eucalypts are grown.

The beetle feeds on leaves, buds and shoots, resulting in stunted growth and deflation and causing heavy losses. It can cause damage over vast areas as it had a great flight capability and gets transferred with transport of forest products.
