Monarch SOS is one of our most popular apps and is enjoyed by users of every age and interest level. It contains beautiful images of monarch butterflies, larvae and chrysalises, and includes annotated slides (see below) that help citizen scientists collect more accurate data for Monarch Joint Venture programs. There are many opportunities for people just like you to get involved in monarch (and other pollinator) conservation programs. Check them out, and take along Monarch SOS to correctly identify monarchs in all life cycle stages, and learn the many species of their larval host plant, milkweed. Many monarch look-alikes are included so you will not only learn why these species are often confused with monarchs, but also where they fly in North America and information about each one. Check out our "What's New?" section of the app. Here you will see what's happening in the world of monarchs and how many conservation organizations are working together to bring back the monarch butterfly!
