Another technique that can be employed to collect fling arthropods is to hold the tail of the net up and approach the arthropods from above with a swatting motion (Figure 3.16). The natural escape behavior of the insect will cause it to fly up and into the net. With either technique the arthropods can be easily confined in the end of the net (Figure 3.17a and b). Care to not disturb the remains should be taken when using a sweep net.
