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. When the sun falls and night begins, nocturnal insects have also evolved with their di- urnal 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 ob- jective of this experiment is to determine which type of light emission and intensity will attract the most nocturnal insects. Methods and Materials The experiment was conducted on the same night, but in different areas of my backyard. Each strand of fly paper was roughly 5 feet apart and descended roughly 2

Similar floor lamps were augmented with 3 different types of bulbs: an LED bulb, an incandescent bulb, and a compact fluorescent bulb. A floor lamp was placed under each piece of fly tape, and stretched about 6 feet into the air; leaving less than a foot of space between the tape and the bulb for optimum illuminessence. The lights turned on a 9:00 pm, and burned until 12:00am. I decided to run all 3 bulbs in the same night to alle-viate multiple sources of error from the uncertainty of Florida weather during the sum-mer. Results The compact fluorescent bulb responded the most varieties of insects as well as the most volume of insects.
