by their odor. This unusual association is not just because the spiders eat their nectar (see the diet section), but also because they play a role in the location for courtship for these spiders. Both sexes of E. culicivora make exaggerated movements when they are on these plants during display, thus presenting with more movements and more variations. The duration of the interaction is also longer. E. culicivora has high specificity in its preference to these plant species, and the odor of these two plants might prime the males and females to meet potential mates. The relationship between E. culicivora and these plants are still largely unknown. Physiology Vision The jumping spiders (family Salticidae) are vision-proficient and have outstanding spatial acuity due to their complex eyes. Salticids use color as cues to make decisions such as classifying prey, identifying landmarks, etc. Color vision of green and ultraviolet are universal among salticids but different species have different mechanisms of achieving certain color vision, and have a different extent to which color vision is inclusive of red. Adult males of the species E. culicivora have bright-red faces. It has been found that the red faces, as visual stimuli, influence adult males' decisions in their behaviors during encounters with other males. The red face is not essential for E. culicivora to be able to identify the individual is a rival conspecific male, but rather, is important for them to decide what to do. When they see a red face, they initiate displaying from further away, and escalate to higher levels of aggression. However, it is unclear if they are sensitive to specifically the brightness, chroma or hue or other factors. Salticidae use their eight eyes for the majority of basic tasks including, hunting, mating, escaping, etc. Their eyes are divided into two sets. One set is considered the side eyes and the other being principal eyes. There are only two principal eyes, which primarily control their vision. The retinae of the principal eyes have four layers of receptors. This layering can be for the examination of the maximum sharpness of objects (i.e. prey). Jumping spiders also have some form of color vision, with each layer responsible for a different color sensitivity/ recognition. In general, jumping spiders are able to see with a high level of spatial resolution that is incomparable to any other species similar to it in size. This explains why jumping
