WebFruit flies undergo a prelude of dances prior to mating. The dance begins when the male approaches the female slowly and vibrates his legs on her head. The next stage of the courtship dance begins when both flies drag their legs from side to side while facing each other. This seems to boost the male's confidence.

WebStudents will study whether fruit flies will move toward or away from important chemicals and food that aid in their survival. Using the choice behavior chamber, behaviors of the fruit-flies are observed and any pattern can be identified. Students will formulate their own theories based on the fruit flies' response to the chemicals and foods.
