Notes

This is a highly specialised Buprestid is adapted to the larger species of Gahnia which are sedges known as Cutting-grasses. It is extremely common and well distributed in regard to its host plant and I have seldom found stands of Gahnia sieberiana in the Mount Lofty Ranges that do not have the tell-tale oval exit holes made by this species on their old flowering stems.
