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 organization 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.
