What do insects primarily use to communicate with each other?

Insects primarily use pheromones to communicate with each other. Pheromones are chemical signals released by insects that can convey a wide range of messages, including signals for mating, marking territory, warning of danger, or indicating food sources. This method of communication is especially effective in the often dense and sensory-overloaded environments where many insects live.

Pheromones can be produced in various forms and have specific effects, allowing insects to communicate complex messages over long distances. For example, female moths release sex attractants pheromones to lure males from a distance, showcasing the efficiency of this communication method.

While insects do use sounds and vibrations (like stridulation or tapping) as methods of communication and can also exhibit body language through movements, these forms are typically not as prevalent or versatile as pheromone signaling. Pheromones enable a broad and nuanced form of interaction that is essential for their survival and social structures.
