Lepidoptera lovers have traded their nets for digital cameras, launched a Web site to track sightings across the country, and raised nearly $250,000 for a 100-acre butterfly garden in Texas. Now the members of the North American Butterfly Association are venturing where only the hardiest naturalists have gone before: into the world of politics. So far, the group has fought to preserve habitat in Pennsylvania and petitioned the U.S. Fish and Wildlife Service to put Florida's vanishing Miami Blue on the endangered species list. "Butterflies will bring a whole new constituency to the environmental movement," says NABA president Jeffrey Glassberg. To learn more, or participate in the sightings program, visit www.naba.org.
