TOUCH COMMUNICATION

Most touching involves the antennae and mouth parts, but not much of information is passed on by this form of communication. Ants often groom each other with their antennae and mouth parts. Honey bees do a waggle dance.  It is in the shape of the number 8 and it is used to give directions on where a new field of flowers is located.

SOUND COMMUNICATION

Sounds are caused by vibrations that can pass through air, water, and solid structures. Although people can hear crickets and cicadas, many insects make supersonic sounds above a person's range of hearing. Sounds can come from the insect rubbing their legs together or from the movement of their wings.

CHEMICAL COMMUNICATION

Many insects communicate with chemicals that are secreted by the insect's glands into the environment. Two of the different types of chemicals messages are pheromones and allomones.
