The Butterfly Guide provides an interactive field guide to over 100 butterfly species in the San Francisco Bay Area, Sacramento Valley & San Joaquin Delta. This app is meant for students, scientists, amateurs, educators, nature-lovers, and anyone who wants a tool for understanding and recording the entomological beauty of our region.

It provides information about butterfly biology, links to host plant records, information about butterfly families and taxonomy, references for additional information and resources, and so much more!

You can also keep track of your own butterfly sightings with The Butterfly Guide's field notebook function. Create "Collections" for use as personal or collaborative butterfly monitoring projects, measuring the butterfly biodiversity in your backyard, or as a tool for sharing nature with kids.

Please check out to learn more about how this app is being used to create a community of citizen scientists and naturalists, and ways that you can be involved in the project's future!
