In this study, we describe a new low-cost technique to collect plant-inhabiting arthropods at a height of up to 10 m without the need for specialized and complicated methods such as rope climbing or fogging. We present a model to build and apply the technique in a tropical forest understory. This technique is important because it is not only efficient for arthropod collection, it also enables a variety of ecological studies such as stratification, habitat comparison, and species distribution.
