Young citizen scientists examine Mexican butterfly weed

November 20, 2013
Young citizen scientists participating in the Monarch Larva Monitoring Project (MLMP) examine a Mexican butterfly weed (Asclepias curassavica), which is in the milkweed family, during their visit to the lab of Karen Oberhauser at the University of Minnesota. Oberhauser, an associate professor in the Department of Fisheries, Wildlife and Conservation Biology, is founder and director of MLMP, a citizen scientist project that involves volunteers from across the U.S. and Canada in monarch butterfly research. The data collected is being used to help explain geographical and temporal variations in North America's monarch populations.
