Inside Insects - Climate Change And Metamorphosis, Cailyn R. Mckay
Undergraduate Student Research Internships Conference
Climate change is causing extreme environmental conditions including an increase in the frequency of heat waves which have the potential to seriously impact insect species, particularly during the sedentary pupal stage. The true armyworm is used here as a model species to evaluate the effects of simulated heat waves on reproductive activity and output later in life. Heat waves had a negative impact on moth reproduction and could be impacting the ecology of the species today and in the future.

Stable Hydrogen Isotopes Of Aquatic-Emergent Versus Terrestrial Insects In Southern Ontario, Celina Y. Tang
Undergraduate Student Research Internships Conference
Aquatic-emergent insects are vectors of both contaminants and nutrients, linking the aquatic system to the terrestrial system. Aquatic-emergent insects are high in omega-3 fatty acids that benefit terrestrial aerial insectivores, such as bats and birds. With aerial insectivores on a decline, a contributing factor could be a decrease in the quality of insects. We collected insects from lakeshore and inland locations in Southern Ontario. Insects sampled included bees, wasps, ants, beetles, caddisflies, craneflies, dragonflies, marchflies, mayflies, midges, other flies, and true bugs. Insects’ wings and powdered bodies were then analyzed for stable hydrogen isotopes (d2H) in order …
