Butterfly Euchloe Ausonides Insulanus

**Wiki:** 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. The Island Marble is white and pale green with a mottled pattern of greenish-yellow under its hind wings. Look in the grassy prairie near wild mustard plants. Don’t confuse it with the more common Cabbage White, which is mostly white with a yellow underside and feeds on the same plants. 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. ...
