It is predicted that extreme weather events due to climate change will result in higher than average streamflow. This study will examine the effects of increased streamflow on the burrowing behavior of the giant mayfly, Hexagenia limbata, in the lab. An array of thin-spaced-chambers will be used to observe the effects of flow rate on the nymphs' U-shaped burrow structure. This undergraduate aquatic entomology research will provide new information about an otherwise well-known species.
