Our knowledge of tropical ant fauna is mainly based on samples collected in forest understory or in the soil. In this study, we describe a low-cost trap which is easy to produce and install to sample arboreal ants in forest vertical strata. We also present empirical evidences of the usefulness and effectiveness of such trap providing an example from results obtained in Pantanal forest patches.
