If a moth detects pheromones how might it work out which direction they are coming from?

Moths detect pheromones using specialized sensory receptors on their antennae. By comparing the concentration of pheromones between their two antennae, they can determine the direction from which the scent is strongest. This differential signal allows them to navigate toward the source of the pheromones, typically indicating the presence of a potential mate. Additionally, they may utilize wind direction and other environmental cues to enhance their tracking accuracy.
