Description
The Regal Fritillary is a large and striking butterfly, known for its vibrant orange and black upperwings, often with a distinctive pattern of dark spots and lines. Females typically have more extensive dark markings and a purplish-black wash on the hindwings. The underside of the hindwings is particularly notable for its rows of large, brilliant silver spots against a dark background, giving it a regal appearance. It is a powerful flyer.
