List three common field traps and briefly state what they target.

Sampling in the field relies on trapping methods that exploit where the insects live and when they’re active. A sweep net is used to collect insects from vegetation by sweeping through foliage, capturing those that dwell on leaves, stems, and in grasses. A pitfall trap sits on the ground, catching ground-dwelling arthropods that move across the soil surface, such as beetles and ants. A light trap draws in nocturnal flying insects by using light, capturing moths and other species that are active at night. Together, these three traps cover vegetation-dwelling insects, ground-dwellers, and night-flying species, offering broad, complementary sampling of insect communities. The other options mix traps with unsuitable targets: pitfall traps aren’t used for canopy insects and sweep nets aren’t for soil-dwelling arthropods; light traps catch nocturnal flyers, not diurnal butterflies. Sticky traps are typically used on plant surfaces rather than soil, malaise traps target many flying insects (not specifically aquatic), and pitfall traps aren’t effective for flying insects.
