Well, do they?
Most insects have a brief courtship that might last for a few hours or even just minutes, followed by mating and egg laying. Often one sex sends out a mating message while the other follows it. This makes more sense than if both sexes randomly fly around hoping to meet. Most well known are crickets, katydids and cicadas, where males sing to call females. Female butterflies and moths attract males from great distances by emitting odors (pheromones) that are carried on the wind and sensed by the male’s antennae.
