A study of about 500 species of lepidopteran caterpillars, beetles and fruit flies details that that most species of herbivorous insects are widely distributed over 75,000 km2 of contiguous lowland rain forest in Papua New Guinea. Thus, although species richness was high, the species found did not alter much even over hundreds of kilometres despite habitat discontinuities and different geological terrains.
