A Tale of Two City
Speaker: Liam O’Brien
Wednesday, September 30, 7:30 pm
Location: Garden Room, Orinda Public Library (directions below)
Known for his conservation work with two of San Francisco’s smallest butterflies, the Green Hairstreak and the endangered Mission Blue, local lepidopterist Liam O’Brien will focus this evening’s presentation on two of our area’s largest butterflies: the Western Tiger Swallowtail and the much-celebrated Monarch. Come learn how behavioral adaptations to the urban environment have pushed these species into new modes of survival. In the shadow of the Xerces Blue—the first butterfly extirpated from the earth due to human development in San Francisco—Liam will propose new ideas on how to improve our legacy with these fascinating and enthralling creatures.
Liam O’Brien was working in ACT’s production of “Angels in America” in the late 1990s when a Western Tiger Swallowtail flew into his yard, captured his attention, and changed his life. Inspired by that butterfly, he has surveyed all of San Francisco County and much of the greater Bay Area to see what remains of our region’s breeding butterfly species. He founded the Green Hairstreak Project to create a habitat corridor for the Green Hairstreak in San Francisco, participated in the effort to restore the Mission Blue butterfly to Twin Peaks, and created the Tigers on Market Street project to inform San Francisco planning decisions about butterfly habitat on that thoroughfare. Liam is also a talented painter and illustrator: His artwork can be seen on interpretive nature signs on many San Francisco Recreation and Parks trails and in the 2012 book The Butterflies of the Presidio (text by Matthew Zlatunich). He received Bay Nature’s Local Hero Award for Environmental Education in 2014.
