This model shows the simulated movement of monarch butterflies on the Iowa landscape. Each curving yellow line represents the flight path of one monarch butterfly as it moves across the landscape laying eggs on milkweeds. The purpose of the model is to examine the benefit of creating small milkweed patches across Iowa. Specifically, what if habitat is improved by adding additional milkweeds to the landscape in roadsides and riparian zones? Watch the video to see how this simple change impacts monarch movement and more!
