 The most significant of these is the Chrysomelid, "Paropsisterna tigrina", but other beetles, cutworm caterpillars ("Agrotis species"), psyllids, mole crickets ("Gryllotalpa"), and others cause significant damage.More than 100 species of insects are known to feed on melaleucas.Native stands have fewer predators, but tea tree sawfly ("Pterygophorus" species) and longicorn beetles are often found.
