Which of the following is NOT a use of insect legs?

The correct choice indicates that collecting nectar is not a primary use of insect legs. Insects typically use specialized mouthparts, such as proboscises, for nectar collection rather than their legs. While some insects might inadvertently transfer nectar while moving, it is not a direct function of their legs.

In contrast, the functions denoted by the other options highlight critical roles that insect legs play in their survival. Climbing surfaces is a primary use, as many insects rely on their legs to ascend various structures or navigate different terrains. Locomotion is a fundamental purpose of legs, enabling insects to move effectively in search of food, mates, or shelter. Grasping prey is particularly vital for predatory insects, which utilize their legs to catch and hold onto their targets, thereby ensuring successful feeding.

Understanding these various uses of insect legs underscores their evolutionary adaptability and the diverse roles they play in an insect’s life cycle and ecological interactions.
