Both adult and larva of the beech buprestid feed on native beech (Nothofagus). The adults eat
leaves and the larvae make broad, shallow mines under the bark of felled or dying trees, or in
dead parts of living trees. Gum-filled mines of newly-hatched larvae may occur in the bark of
trunks and branches of living trees, especially those which are suppressed or subject to seasonal
droughts. If the newly-hatched larvae reach the cambium of living trees gum flecks may become
included in the wood and will cause a minor timber defect.
