Abstract Nocturnal insects have impeccable vision systems that have evolved to decipher color change and orientation and navigation enhancement. (Warrant, 2011). Insects with compound eyes have more advantage over simple eyes, because they are able to dis- tinguish their surroundings more efficiently when it comes to environment and predators. The compound eye of insects is made up of ocelli and ommatidium, which contain photoreceptors. All three types of photoreceptors are graded to light intensity (Horridge, 2009). These receptors balance the response in such a way that the insect is able to de- cipher between changes in brightness. When the sun falls and night begins, nocturnal insects have also evolved with their diurnal relatives because of their visual ability. A mixture of behavioral modifications and high optical sensitivity allow for their accuracy and precision to occur at night. The objective of this experiment is to determine which type of light emission and intensity will attract the most nocturnal insects. The three
