    Abstract
    Naturalized exotic species are homogenizing the earth’s biota and are increasing densities of pests in newly colonized areas. When exotics change ecosystems and affect native species, then they are invasive. Do high density populations of Spathoglottis plicata (a naturalized orchid) affect populations of Bletia patula (a native orchid) through a common florivorous, orchid specialist weevil, Stethobaris polita. We will determine the effect of S. plicata on the reproductive success of B. patula when S. plicata is present at variable densities. In addition, we will determine the florivory preference of weevils between S. plicata and B. patula. Finally, we will create a distribution model map for both orchid species, to predict the localities where both species may be interacting.
