Fractal time in animal behaviour: the movement activity of Drosophila

The activity and inactive organisms of Drosophila melanogaster have a complex structure. Short inactive events are embedded in events that appear to be continually active on the surface. This activity mode has a self-similar structure, and the activity record shows the same thing regardless of the time scale used. The rate "constant" has a law dependency to describe how fly activity is turned on and off. Therefore, there is no natural time scale for measuring the activity level, and the activity amount depends on the measured time scale. Observing the fractal time change of animal's behavior can clarify the process of creating the activity. Fractal time change in athletic activity leads to Levy flight movement pattern, which may result in efficient search.

The following sections are based on Drosophila species: Drosophila simulans and Drosophila melanogaster. Courtship behavior of male fruit fly is an attractive behavior. Women respond to their perception of male behavior. Male and female fruit flies use a variety of sensory cues to initiate and evaluate spousal candidate mothers using congenital and complex behavior. Behavior itself, trying to copulate, trying to hint, behavior, excretion of pheromones, female behavior, leg striking, singing, wing spread, wing vibrations, reproductive warts, abdomen bending, mating. Drosophila melanogaster and Drosophila simulans songs are widely studied. These fascinating songs are essentially sinusoidal and vary among species and species. In recent experiments, the roles of fruitless (fru) and double sex (dsx), a group of genes related to sexual behavior, have been investigated.
