Leaf damage to Rhizophora mangle L., Avicennia schaueriana Stapf. & Leechman, and Laguncularia racemosa L. was studied in a two hectare mangrove swamp site in Sepetiba Bay. Seventeen arthropod morphospecies were identified as being responsible for the damage, and their species diversity was highest on A. schaueriana, followed by R. mangle and L. racemosa. Damage in terms of relative area was greatest in L. racemosa. Almost 9% of mangrove canopy leaf area demonstrated some damage. Loss of leaf area to herbivory was 12.1%, 8.3% and 6.2% in L. racemosa, A. schaueriana and R. mangle respectively. L. racemosa and A. schaueriana showed high percentages of leaf-margin damage in terms of the total damaged leaf area (82.2% and 56.3% respectively), while the most important type of damage in R. mangle was necrosis, representing 58.1% of the total damaged leaf area.
