Eucalyptus Long-horned Borer

Phoracantha semipunctata


About 3.5cm long with a 9cm antennae span. Distinct dark bisection of light coloured patch on wing.


This specimen was found in the CBD on a busy footpath. 'The larvae of the Eucalyptus Long-horned Borer attack Eucalypt trees. They mostly attack stressed or damaged trees. Evidence of borers includes holes in the bark and oozing fluid on trunk or branches. In severe cases foliage may wilt and limbs die back. They rarely kill healthy trees.'
