TEMPORAL FRACTAL IN THE FEEDING-BEHAVIOR OF DROSOPHILA-MELANOGASTER

A temporal fractal is clearly shown in the feeding behavior of Drosoph ila as a self-similar pattern of locomotive velocity and inverse power law distributions of food dwelling time over the time scale range of 10(3). The fractality was observed in the dwelling time distribution i mmediately after the fly was placed to feeding site or on inferior foo d in a two-choice situation. Fractality may be understood as adaptive, and an intrinsic property of animal behavior that reflects complex in formation processing in the CNS of Drosophila.
