to the adaptation and use of characteristics of the living being that explain its desire to target a specific type of prey. The specific desire for Anopheles mosquitoes was supported when presented with two blood-carrying mosquitoes of different genera: the Anopheles was consumed by both adults and juveniles. Juveniles would choose the Anopheles over all other prey regardless of whether it actually was carrying blood. When presented with a blood-carrying mosquito, regardless of species, E. culicivora would consume the blood-carrying one. Small juveniles choose smaller prey while adults choose larger prey. E. culicivora may be adapted to choose prey that are easy to capture. However, their preference for blood takes precedence over their preference for size. The prey-choice behavior of E. culicivora is innate, and they can make highly specific prey identifications by sight or odor alone. This preference was not absolute, as starved or significantly more hungry spiders were less discriminating and would consume whatever prey they were presented. Role of scent E. culicivora is likely to be the only known animal that targets its prey according to what it senses that the prey has eaten. E. culicivora’s sharp senses allow them to be one of the most picky predators in nature, and especially within this family of spiders. E. culicivora is known to be attracted to the smell of bloody mosquitoes and also human feet, and they themselves sense their more luring smell after a large blood meal. Additionally, these spiders are able to detect and pounce on their prey correctly even without scents because of their strong ability to distinguish between visual cues through the receptor system in the eyes. The large front pair of eyes are highly reactive to stimuli and contain over a thousand receptors in adults and over three hundred receptors in young, making E. culicivora a choosy eater throughout their life cycle. Non-predatory feeding Hunting spiders including salticids supplement their predatory diet with nectar, and nectar meals are important alternative food resource when prey are not sufficient. This is because fructose is a significant component of their diet and the attainment of fructose comes primarily from the consumption of nectar. Younger spiders might benefit more from nectar consumption simply because the amount of nectar obtained from these plants may be sufficient for the smaller individuals but not for the larger spiders. Consequently, nectar consumption may be more suited as a meal substitute for
