Euchloe ausonides insulanus, the island marble butterfly, is a subspecies of butterfly found in the San Juan Islands in Washington in the northwestern United States.
In 1998 the island marble, thought to be extinct since 1908, was discovered during a prairie butterfly survey in San Juan Island National Historical Park.[1]
The Canadian Species at Risk Act (SARA) listed the island marble butterfly as being extirpated in Canada in May 2000 and again in April 2010.[2]
On August 22, 2012, the Xerces Society for Invertebrate Conservation submitted a petition for protection with the US Fish and Wildlife Service (USFWS).[3][4] Although not yet listed as endangered, the island marble butterfly is currently noted on the Washington State Species of Concern List.[5] In April 2018, the USFWS proposed to list the butterfly as endangered.[6]
On May 5, 2020, the island marble butterfly was listed as endangered under the Endangered Species Act of 1973.[7]
