none no species Main leaf damages to Eucalyptus cloeziana trees were characterized by the linkage of leaves with silk spun by caterpillars of Lethata anophtalma, Antaeothrica sp., Cerconota sp. and a non-described Tortricidae species. On average, 40% of the trees were damaged. Leaves mined by a non-described Gracillaridae species were found in about 15% of the trees. About 13% of the most abundant caterpillars, L. anophtalma and Antaeotricha sp., were parasitized. L. anophtalma was parasitized by Paraolinx sp. 1 and P. sp. 2, Horismenus sp. 1 and H. sp. 2, Sympiesis sp. 1 and S. sp. 2, Cirrospiloideus sp. (Hym: Eulophidae) and Eumasicera sp. (Dip: Tachinidae). Antaeotricha sp. was parasitized by Bracon sp. and Orgilus sp. (Hym: Braconidae). Fluctuation curves of the damage levels through time and those curves on the phenology of L. anophthalma showed a close synchronization within plots, but not between plots. The capture of the L. anophthalma parasitoids by Malaise traps coincided with the population peaks of their hosts.
