    Introduction Flesh fly larvae, Sarcophaga sp, possess a photoreceptor located on the larva I s anterior end. From this, a further observation was made that fruit fly display a distinct orientation, generally moving away from light. Our experiment is meant to test the validity of the hypothesis that flesh fly larvae move away from light. The experiment hence establishes a relationship between light intensity and the orientation of the flesh fly larvae from which an explanatory system can be generated. The experiment is based on deductive reason to prove that increase in light intensity will result in a corresponding increase in the distance moved by the fresh fly larvae.

    Methods In order to observe the effects of light  intensity on maggot displacement we  measured maggot displacement after 10  seconds under a black cap followed  immediately by 60 seconds under specific  light intensities.  The displacement was measured by the  maggots movement over concentric circles,  with radii increasing by one centimeter as  printed on their paper surface.
