My primary role in the Norris lab ( is to manage two of the monarch butterfly projects. Previous research suggests that recovery of declining monarch butterflies (a species-at-risk in Ontario) depends on the availability (both quantity and quality) of milkweed plants, the only food plant for monarch butterfly caterpillars. The objective of the first project is to develop optimal management strategies for milkweed in right-of-ways for monarch butterflies. Evidence that neonicotinoid pesticides are a threat to many pollinator species has made it also important to understand the effects of these pesticides on monarchs. For the second project, I’m studying the effects neonicotinoids on monarch breeding and migration in an agricultural setting with milkweed growing alongside neonicotinoid treated corn.
