• Dark brown to brownish orange beetle.
• Adults are 11–20mm long.
• Antennae are long.
• Elytra (wing cases) are covered in irregularly distributed hair.
• Larvae are yellowish-white with brown heads, wrinkled skin.
• Larvae up to 20mm long.
• Eggs are white, elongated, rounded at the ends.

• Life cycle can take 1 or more years to complete.
• Requires trees with intact bark to reproduce in.

• Host range of over 40 genera of coniferous and deciduous trees including mulberry, apple, pine, ash and willow. Host material can be healthy, stressed, dying or cut trees including structural timber in buildings.

Environmental

• The larvae tunnel within the trunk and larger branches of trees which leads to a thinning crown, yellowing leaves and eventually death of the tree.
• Will potentially affect a range of native trees and forests.

Economic

• The damage caused could lead to reduced fruit yield, lower quality wood and shorter tree lifespan.
• Could especially affect the apple, pear, grape and pine industries.

Social

• Could affect amenity trees such as those used for street plantings, in parks and on private properties.

• The Chinese longhorned beetle is not a prohibited or restricted invasive animal under the Biosecurity Act 2014. However, by law, everyone has a general biosecurity obligation (GBO) to take reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control.
• Local governments must have a biosecurity plan that covers invasive plants and animals in their area. This plan may include actions to be taken on certain species. Some of these actions may be required under local laws. Contact your local government for more information.
