The extraordinary diversity of insects in tropical forests translates into even larger diversity of their trophic interactions in plant-herbivore food webs. Here we describe the challenges of food web censuses in tropical forests, using examples from our field work in Papua New Guinea, and explore experimental and analytical approaches to their analysis. In particular, we are interested how are local food webs assembled from regional species pools and how they maintain their complexity, in comparison with analogous food webs from temperate zone forests. We also provide some notes on challenges and adventures of ecological research in Papua New Guinea.
