    predict certain behaviors. Dr. George W. Uetz has taken what might be perceived as natures dance of survival to an extreme: While most people automatically picture a lion tracking  down a hapless antelope as being representative of the predator-prey interaction, Uetz et al (2002) have brought to light an entirely different approach by way of studying the impact of  sarcophagid flies (Arachnidomyia lindae) upon the egg sacs of the colonial orb-weaving spider (Metepeira incrassata). The author delves deeply into the reasons why the sarcophagid fly presents as the  primary predator of colonial orb-weaving spider egg sacs, utilizing past studies to support his own thesis and subsequent research. "While previous studies have shown that this colonial web-building spider  uses a number of general attack-abatement mechanisms against a diversity of predators and parasitoids, results of this study suggest that selection pressures from a highly specialized predator may also result  in evolution of predator-specific prey responses" (Uetz et al, 2002, pp. 51-60). At the crux of Uetz et als (2002) hypothesis is the manner by which the spider has  the capability of establishing certain and distinctive mechanisms that help to identify which predator has come into her web. This adaptation for survival illustrates how ingenious the spider is  when it comes to protecting the progeny that reside in the egg sacs, stemming from the perpetual evolutionary components intertwined with the predator-prey relationship. Indeed, the extent to which  the sarcophagid fly will continue to ravage the colonial orb-weaving spider egg sacs is indisputable; however, Uetz et als (2002) research clearly shows how this evolutionary process is inherent to  the spiders quest to better equip herself against the web raiders. "Since colonial spiders may deposit their egg-sacs at the web-site, many species have also evolved active maternal defense
