The island marble butterfly may get protected under the U.S. Endangered Species Act, thanks to a new settlement agreement between the U.S. Fish and Wildlife Service and The Xerces Society for Invertebrate Conservation.
The Xerces Society, based in Portland, has been working for years to study and protect the green and white butterfly, one of the rarest species in the U.S. It has already vanished from Canada and now is only found on San Juan and Lopez islands in Washington state.
