What is the primary goal of canopy fogging in ecological studies?

The primary goal of canopy fogging in ecological studies is to capture insects in high tree canopies. This method involves using a fogging solution to create a mist that penetrates the upper layers of forests, where many insect species reside. By applying this technique, researchers can collect and identify insects that may not be easily accessible through ground-level sampling methods. Capturing these insects provides insights into the biodiversity and ecological interactions present in the canopy layer, which is vital for understanding ecosystem dynamics and the roles of different species within their habitats. This approach is particularly important because the canopy hosts a vast number of species, many of which are not yet fully documented or understood.
