Thanks Kim! This one had me stumped for a long time, so I took my time before adding it to CNM. Are there any particular species of tree/shrub they prefer? Some of our acacias near the house were destroyed by unknown borers (and happy black cockies) over the past year or two.
Information in 'Australian beetles' Vol. 1 by J.F. Lawrence & A. Slipinski (CSIRO Publishing, 2013) only says the larvae "bore into hard wood of weakened or dead trees and feed on Ambrosia fungi". The female actually carries spores of the fungus in special pouches and infects the tree as it lays eggs. Incidentally the common name comes from a European species of the family, which attacks timber used in ship building.
