Butterflies: Viceroy

Though more closely related to White Admirals and Red-spotted Purples, Viceroys (Limenitis archippus) are most often confused with similarly colored Monarchs. To separate the two, note the black median stripe across the rear wings of the Viceroy, a field mark not present on Monarchs, or from a distance, watch how they fly. Viceroys tend to glide with wings held flat, unlike Monarchs who usually glide with their wings in a V shape.

Larval plants for Viceroy caterpillars include various Willows (Salix spp.) and Poplars (Populus spp., including Big-toothed and Quaking Poplar). Adults are widespread in New England during the green season.
