Specified RTUs of captured insects in grasslands region.

For this experiment, the sweep-net procedure was used. The experiment aimed to capture insects with vigorous net-sweeping action along specified transects. The distance walked along the transect each time was 25 meters for a total of 10 times. The targeted insects were located in the grasslands at York University. Once a single transect was complete, the net was held open and the captured insects were observed and identified according to their RTUs (recognizable taxonomic units). For each capture, the number of insects in each RTU were visually counted and recorded. This method was repeated 10 times in the grasslands and resulted in a total sample size of 54 captured insects.
