Insects show a variety of species-specific innate behaviors (instinctive behaviors). For example, a worker honeybee that has found flower nectar exhibits 8-shape waggle-dances upon returning to its beehive. A male moth that has detected a sex pheromone flies around to look for a female counterpart. There remain a number of questions about how a variety of innate behaviors are generated by functions of neural circuits in the insect brain.
