Insect Behavior

• Insects sometimes live alone.
• However, many insects live in large colonies
  (ants, bees, wasps, etc.)
• Insects must often communicate with each other.
  One method is the use of pheromones.
• Pheromones are extremely powerful chemicals
  released by insects to communicate. These can
  sometimes be sensed a mile away.

  is to find other members of your species by the
  smell of the pheromones given to you.
