Ophryocystis elektroscirrha, a protozoan parasite, can have many different effects on the Monarch Butterfly, Danaus plexippus, including difficulty emerging from the pupal case and spreading their wings, and increased mortality within 24 hours of eclosion. Color in the wings of the butterfly is a strong indicator of fitness in terms of reproductive success. In this study I test if parasite load has an effect on the fitness of individuals of D. plexippus using color of the wings as a proxy for fitness. I measured the wingspan; asymmetry of forewings; color hue, saturation, and brightness; and parasite load on 15 individuals of D. plexippus. There was a trend in the differences of the wingspan averages between infected and uninfected individu...
