Naturalist Amber Hasselbring and citizen scientist and professional researcher, Liam O'Brien see themselves as butterfly warriors. The Western Tiger-Swallowtail Butterfly seen here is one of the species common to the Market Street area of San Francisco. According to O'Brien, Hasselbring and others like naturalist John Muir Laws, "Butterflies see city streets as 'canyons' where they can rest (on trees) and feed."
