Final answer:
The experimental procedure designed to investigate the function of wing markings and waving in the context of insects like butterflies is to conduct observations and comparisons between insects with intact wings and those with damaged wings.
Step-by-step explanation:
The experimental procedure designed to investigate the function of wing markings and waving in the context of insects like butterflies is to conduct observations and comparisons between insects with intact wings and those with damaged wings. By comparing the behavior and flight capabilities of these two groups of insects, researchers can determine the function of wing markings and waving.
