The lizard used the optimal foraging strategy based on their environment behavioural rule to yields the maximum amount of food for their survivability.
A lizard used the foraging strategy to capture the prey based on their criteria or policy to minimize the average time to catch the prey based on per captured item of prey. In this paper, assume that insects appear probabilistically within 180° planar area visible from the lizard's perch. If insects within the lizard viewing area, it would advantageous for the lizard to chase every nearby insect. However, if any prey outside of the lizard perch and the lizard will be away from its perch for so long time, it will go for nearby insects. This suggestion ignored the distant
