Ophryocystis elektroschirrha (Neogregarinda: Ophryocystidae), is a parasite found in populations of monarch (Danaus plexippus) and queen (Danuas gilippus) butterflies (Lepidoptera Nymphalidae Danainae) (Altizer & Oberhauser 1997, Altizer et al. 2000, Leong et al. 1997, Vickerman et al. 1999). The parasite has both asexual and sexual stages in its lifecycle, and produces spores while the butterfly is pupating (Yixian Yueh 2005). Larvae become infected when they consume leaves or egg shells contaminated with spores. High densities of spores restrict body size and can reduce fecundity and life span in male adults (Altizer & Oberhauser 1999). This study investigates whether the parasite occurs on other species of butterflies. One hundre...
