Caterpillar foods: Cherry, willow, birch and some other trees and shrubs (Bugguide)
This is one of the color variations of Limenitis arthemis, and is found in the NE United States and SE Canada. The two color variations I’ve seen here at the farm are L. arthemis arthemis (White Admiral), and L. arthemis astyanax (Red-spotted Purple). We see many Red-spotted Purples but very few White Admirals.
