I am currently exploring how butterflies respond to heat waves. I have four treatments that are administered to Baltimore checkerspots: a control, a high level heat wave, a high level but long lasting heat wave, and a low level heat wave. The objective of the experiment is to determine how degree and duration of heat waves affect survival. After doing so, I will search through databases to determine the average duration and temperature of heat waves in areas inhabited by checkerspots. Next, I will look for future estimates on heat wave duration and temperature. I should hopefully be able to compile that information into a prediction for how Baltimore checkerspots, the endangered state insect of Maryland, will cope with climate change and the ensuing increase of heat wave duration and intensity.
