Aquatic insects begin life as larvae in the water, growing and gathering resources before they emerge as adults on land to reproduce. This transition between water and land links the two habitats, as the adult insects become food for bats, birds, and reptiles. When aquatic habitats are stressed, as by contaminants, this link can be broken by way of reduced insect emergence to land. Our goal is to find out what happens to these insects when agricultural contaminants get into the water.
