The Las Vegas Wash Coordination Committee has been assisting in the Southwest Monarch Study. The goal of the study is to provide information on the migration and breeding patterns of monarch butterflies across the Southwest.
Once volunteers capture monarchs using nets, they carefully apply a small sticker with identifying information to their wings, allowing individuals to be identified and tracked through the course of their migration. The monarch is currently under consideration for protection by the U.S. Fish & Wildlife Service due in large part to a loss of habitat and milkweed, the caterpillar's only food source.
