Text and provided by Mark Hoddle, Director of Center for Invasive Species Research, Extension Specialist Female beetles lay their eggs under loose bark, and when the eggs hatch, the young larvae burrow through the bark layer and into the cambial layer which lies just below the bark. Environmental Entomology, 20(6):1583-1588, Hanks LM, Paine TD, Millar JG, 1993. Entomologist's Monthly Magazine.

Summary of the control programme using trap trees. The parasitoids pupate inside the host tunnels and upon completion of development they emerge from host trees to commence mating and host searching. They are characterized by prominent long antennae, an obvious feature that is characteristic of cerambycid or long horn beetles. Chararas C, 1969.

Wallingford, UK: CAB International, 113-129. Phoracantha semipunctata [on eucalypts] in southwestern Spain. Female beetles lay their eggs on the sprayed logs which are replaced every 2 weeks with fresh ones. Eggs are usually protected from exposure to pesticides, because they are laid under layers of loose bark. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. Hanks LM, Paine TD, Millar JG, 1991. (Coleoptera: Cerambycidae) in Australia.

Water relations of host trees and resistance to the phloem-boring beetle Phoracantha semipunctata F. (Coleoptera: Cerambycidae). Paine TD, Millar JG, 2002. Eucalyptus Longhorn Borer Home Arborist Advice A swift decline in tree health, as exhibited by branch and twig death, leaf discoloration and leaf drop might indicate the presence of the eucalyptus longhorn borer. The eucalyptus longhorned borer (ELB) was first identified in California in 1984 and has since killed thousands of eucalyptus trees. The adults are active during the greater part of the year and it would, therefore, be necessary to use pesticides with long residual effects or to make frequent applications to kill beetles landing on the tree. Recommended preventive measures are concerned with managing the forest in such a way that trees are kept in good health. Hanks LM, Millar JG, Paine TD, Wang Qiao, Paine EO, 2001. Appl. It is a vital part of the enviromemt in Australia however in California, USA, it has been classified as an invasive pest species of eucalyptus originating from Australia.
