Editors Note: This post by SciStarter contributor Eva Lewandowski describes her experiences with citizen scientists from the Monarch Larva Monitoring Project, which was featured in our recent Spring themed newsletter. Check out the rest of the projects on that list here. The Monarch Larva Monitoring Project is also one of more than 800 citizen science projects on SciStarter.

What do citizen scientists gain when they collect data for a research study? What do they learn, and how does it change them? These are some of the questions that I try to answer in the course of my PhD research. As a graduate student in the University of Minnesota’s Monarch Lab, I have an up-close view of our lab’s citizen science project, the Monarch Larva Monitoring Project (MLMP), which has given me an excellent opportunity to find out how citizen science affects the citizen scientists themselves. Over the past few years I’ve spent a great deal of time meeting, writing about, and studying our MLMP volunteers. More often than not, what strikes me about these interactions is the volunteers’ familiarity with and connection to their monitoring sites. At the MLMP, we study how the population of monarch butterflies varies in space and time; given the dramatic decline in monarch numbers over the past decade, it’s more important than ever that we understand the factors impacting the monarch population. Each fall, monarchs west of the Rocky Mountains migrate to the California coast to overwinter, while the monarchs east of the Rocky Mountains travel thousands of miles to Mexico, where they spend the winter. In the spring, the monarchs in Mexico begin to make their way north throughout the United States and Canada, going through several generations before they reach their northern-most destinations. Once there, they continue to reproduce until it is time for a new generation to fly south the Mexico. Throughout the breeding season, MLMP volunteers across North America monitor milkweed patches weekly for monarch eggs and larvae. Volunteers choose their own sites, and the only requirement is that it has milkweed; monarch butterflies will only lay their eggs on milkweed, so it must be present if you hope to find monarch eggs or caterpillars. Milkweed isn’t as prevalent as it once was, but it can still be found in gardens, parks, pastures, and roadways, so volunteers don’t usually have trouble finding a patch to observe; those that do can plant their own milkweed. In addition to counting the number of eggs and larvae that they see, volunteers also provide data on the number and types of milkweed and flowering plants at their site.
Because MLMP volunteers monitor the same milkweed patch week after week, and often year after year, they are usually extremely familiar with their site.Most can tell you off the top of their heads what species of milkweed and nectar plants they have, as well as when they come up and when they bloom; many also know which plants are the monarchs’ favorites and which are preferred by other insects. And because monitoring for monarch eggs and larvae involves carefully examining the leaves of milkweed plants, volunteers encounter a lot more than just monarchs on their milkweed plants. From soldier bugs to milkweed beetles to aphids, MLMP volunteers are familiar with a wide variety of insects that make their home on or around milkweed. Many MLMP volunteers can use the field guide Milkweed, Monarchs and More, coauthored by MLMP Director Dr. Karen Oberhauser, to identify and learn about the flora and fauna commonly found in milkweed patches. The book focuses mainly on plants, insects, and arachnids, but our volunteers also enjoy observing birds, amphibians, and mammals while collecting data. Participants often snap a picture of the interesting animals they see in their plots to contribute to the MLMP Photo Gallery, such as when long-time MLMP volunteer Jan Sharp found herself “eye to eye” with a tree frog perched on her milkweed, or when Diane Rock stumbled across a black bear in her milkweed patch. Observing and learning about the plants, animals, and overall ecosystem of their monitoring site is one of the best parts about being an MLMP volunteer, but our volunteers also love that they can share that experience with others. Many of our participants monitor with children, usually their own or their grandchildren, which gives them a chance to connect young people to nature. We even have a few second-generation MLMP volunteers, people who started monitoring with their parents and now monitor their own site or have taken over the original site. MLMP is so much more than just collecting data on monarch abundance. It’s an opportunity to get outside, to learn about a piece of land and everything that lives on it, and to share that connection with others. We’re always in need of more volunteers; if you’re looking for a chance to get outside and connect with nature, while making a meaningful contribution to science and conservation at the same time, join the MLMP!
