## What is Monarch SOS?

Monarch SOS is a field guide for the public as well as a citizen science reporting app. It is the first monarch app developed by scientists that covers monarch identification in all life cycle stages, confusing look-alikes and numerous milkweed species (monarchs' larval host plants), frequently encountered in North America.

Monarch SOS is a valuable tool for learning about monarch butterflies, threats they face and how everyone can help bring back the monarchs by making a few simple lifestyle changes. 

If viceroy and queen butterflies confuse you, quickly learn the differences in the "Compare" section under each butterfly. Keep up with the latest information on monarch conservation efforts and migration news by checking in daily with What's New? The feed is updated every time you open the app, so you'll always be in the loop!
