Foliar insect damage levels on woody sprouts in the ground layer of 2 tropical eucalypt forest communities on Melville Island were between 7.8 and 43.2 percent. Of 8 common tree species, Eucalyptus confertiflora was damaged most by insects and Buchanania obovata and Terminalia ferdinandiana the least. Seasonal trends in insect damage were not consistent between plant species and were not always consistent between vegetation types for a particular plant species. The results of this study are not consistent with hypotheses suggesting that insect grazing is a critical determinant of tree species dominance or woody sprout dormancy.
