Sweep nets are used to collect which of the following?

Explanation:
Sweep nets target arthropods that live freely on vegetation surfaces. By sweeping the net through crops or other foliage, you dislodge and capture both adults and immature stages that inhabit leaves, stems, or flowers, giving a quick indication of foliar pest pressure. This method isn’t used for soil-dwelling larvae, which require soil sampling tools, nor for aquatic insects, which need water-based nets, and birds are vertebrates not collected with this type of net.
