A Tale of Two City Butterflies with Liam O’Brien

  • Garden Room at Orinda Public Library 26 Orinda Way Orinda, CA, 94563 United States (map)

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.
