American Lady Vanessa virginiensis

Often overshadowed by its famous cousin, this butterfly is every bit as remarkable—and much rarer in some parts of North America. The key difference? Look at the hindwings: where Painted Ladies have four eyespots, this species has just two, and they're usually much larger. Like its more common relative, it's a globe-trotting migrant with an almost unlimited appetite for plants, capable of colonizing new habitats faster than you'd think possible. It's the subtle variations that make nature's family trees so fascinating.
