Recent studies have provided evidence that spiders’ color and pattern may attract prey items to their webs, thus increasing
their foraging success. However, these studies were conducted on tropical spiders, and no studies have examined this phenomenon
in temperate spiders. We examined the role of color and pattern in a North American spiny orb-weaver,
Micrathena gracilis. We found that prey capture rates were similar between webs that contain spiders and webs in which spiders were removed.
Additionally, we found a trend that painted spiders captured more prey than unpainted spiders. Although our results were not
statistically significant, they contradict previous studies examining the role of color in prey attraction.
