Abstract
The aphid Myzocallis asclepiadisis a relatively unknown species that feeds on the common milkweed Asclepias syriaca. This aphid is very mobile and mobility appears to be the primary defense against predators. However, over the course of the summer, the aphid changes color, from a pale yellow-green to having orange spots. This aphid could be a model to answer the question of how aposematism evolves. In this study, a natural, unmanipulated population of My. asclepiadisis was monitored, and experiments manipulating development and density to determine the nature of the color change were conducted. However, it does not appear that development and density are cues for color change. Photographic analysis of color and HPLC analysis are underway to determine the extent of color change and whether that change corresponds to an increase in cardenolide sequestration.

Abstract
Coexistence of host-specific herbivores on plants is believed to be governed by interspecific interactions, but few empirical studies have systematically unraveled these dynamics. We investigated the role of several factors in promoting coexistence among the aphids Aphis nerii, Aphis asclepiadis, and Myzocallis asclepiadis that all specialize on common milkweed (Asclepias syriaca). Competitive exclusion is thought to occur when interspecific competition is stronger than intraspecific competition.

Summary
1. Dietary specialization in insect herbivores has long been hypothesized to predict tolerance of plant defenses, with more specialized herbivores being highly tolerant of and sometimes sequestering plant secondary compounds. Plant variation in secondary compounds should thus play an important and predictable role in shaping the performance and distribution of insect communities.
