Web-building spiders are sit-and-wait foragers. This means that they are relatively inactive and create traps for their preys. Spiders strategize the location and density of their web to maximize the number of prey that are captured. The types of insects spiders capture are attracted to light. Most spiders will build their web close to a light source to increase their probability of catching the maximum amount of prey. In addition, spiders may be genetically determined to be attracted to light because they use reflected moonlight to find high insect densities (Heiling 1999).
