Host plant notes

Adults have been collected from two species of Beard-heaths Leucopogon, with large numbers found on one of these, Ruddy Beard-heath L. rufus. It is suspected that Leucopogon and possibly other Heaths (family Ericaceae, formerly Epacridaceae} may be larval hosts. There is some support for this with a dead larva of subfamily Agrilinae being discovered in the stem base of a L. rufus plant on which adults had previously been collected.
