Liam O'Brien has spent three decades chasing, learning about, protecting, occasionally catching, and always loving butterflies. Here, he shares his capacious knowledge of California butterflies through a treasure trove of stories and 700 gorgeous, hand-drawn illustrations – featuring both adult forms and caterpillars – of the 135 species that live in the greater Bay Area. This sumptuous book also shares practical tips for finding and identifying all the butterflies that call the Bay Area home. Learn which plants nurture Silver-spotted Skippers, which trail to hike to see Swallowtails flitting creek-side, and why so many butterflies cluster on hilltops. Share in the joy that O'Brien brings to the study of butterflies, and join the community scientists contributing to our understanding of Monarchs, Metalmarks, and Marbles – and what they need to survive and thrive in our busy Bay Area.

About the Author
A Note on Type
Liam O'Brien is a self-taught lepidopterist and illustrator. He used to be a professional actor, having appeared in Les Misérables on Broadway, but shifted his powers of observation towards nature several decades back. He's fascinated not only by butterflies but also by our relationships to them. He surveyed the county of San Francisco, where he lives, for which butterfly species remained in 2007 and 2009. He is the creator of the Green Hairstreak Project for the organisation Nature in the City, and he led efforts to restore Variable Checkerspots to the Presidio. Since 2015, he has helped monitor the endangered Mission Blue butterfly in the Marin Headlands. O'Brien was the recipient of Bay Nature magazine's Local Hero Award for Environmental Education in 2014. He lives in San Francisco.
"If you live in the Bay Area and wish to know the butterflies, this is the only field guide you'll ever need. Liam O'Brien is a passionate observer, a talented artist and a dedicated ecologist who, among other things, helped reintroduce the Variable Checkerspot to the Presidio. If they gave this book to every high school graduate in the state, it would be a classic within a generation."
– Lewis Hyde, author of The Gift
