During the time of the American Revolution, while many people were focused on tea and taxes, some North American butterfly enthusiasts, known as lepidopterists, were more interested in studying butterflies. As the redcoats and rebels were preparing for battle, these butterfly lovers were busy collecting specimens, including two new species in the genus Limenitis. One of these was the White Admiral, a black butterfly with striking white stripes. This butterfly is mainly found in what is now Canada and is the official insect emblem of Quebec. Further south, in what would become the USA, there was another butterfly with yellow-orange spots and blue, black, and brown markings, which was named the Red-Spotted Purple. Today, this butterfly is recognized as New York State’s official butterfly.
Even though their names might not seem entirely accurate, each butterfly has its own unique way of surviving. The White Admiral, true to its name in one way, uses its black and white stripes to blend into its surroundings, making it harder for predators to spot. It’s like a stealthy commando in a combat zone. On the other hand, the Red-Spotted Purple wants to stand out. Its bright colors mimic those of another poisonous butterfly species, tricking predators into thinking it’s dangerous to eat.
For a while, it was easy for lepidopterists to tell these two butterflies apart. They had different wing patterns, survival strategies, and lived in mostly separate areas. But something interesting happens near the U.S.-Canada border, where the habitats of these two butterflies overlap. Here, you can find butterflies that have both colorful spots and white stripes, looking like a mix of the Red-Spotted Purple and the White Admiral. These are actually the unique offspring of the two species.
This discovery made scientists rethink whether the White Admiral and the Red-Spotted Purple were more similar than they appeared. Even though they look different, these butterflies are surprisingly alike in many ways—genetically, anatomically, and behaviorally. In fact, they mate with each other in the wild just as easily as they do with their own kind.
All these factors eventually led scientists to classify the two butterflies as one species. This shows that appearances can be misleading, not just in butterflies but in many other species that live across borders. Nature is full of surprises, and sometimes, what seems different on the outside can be very similar on the inside.
Create a diorama that represents the habitats of the White Admiral and the Red-Spotted Purple butterflies. Use materials like paper, clay, and paint to show the different environments where these butterflies live. Think about how their colors help them survive in these habitats. Share your diorama with the class and explain how each butterfly’s appearance helps it adapt to its surroundings.
Participate in a role-play activity where you act as a scientist discovering the genetic similarities between the White Admiral and the Red-Spotted Purple. Work in groups to create a short skit that demonstrates how these butterflies can interbreed and produce offspring with mixed traits. Present your skit to the class and discuss what this tells us about species classification.
Conduct an experiment to understand how camouflage and mimicry work. Use colored paper to create butterfly cutouts and place them in different environments around the classroom or schoolyard. Observe which colors blend in best and which stand out. Discuss how these observations relate to the survival strategies of the White Admiral and the Red-Spotted Purple.
Create a timeline that traces the history of the White Admiral and the Red-Spotted Purple from the American Revolution to their reclassification as one species. Include key events, such as the discovery of their overlapping habitats and the genetic studies that led to their reclassification. Present your timeline to the class and explain how scientific understanding has evolved over time.
Engage in a debate about the classification of the White Admiral and the Red-Spotted Purple as one species. Divide into two groups, with one arguing for their classification as separate species and the other arguing for their classification as one. Use evidence from the article and additional research to support your arguments. After the debate, discuss how scientific classification can change with new evidence.

Around the time of the American Revolution, some North American lepidopterists were focusing more on butterflies than on tea and taxes. As the redcoats and rebels squared off, the butterfly enthusiasts gathered their own collection of specimens, including two new species in the genus Limenitis. One was the White Admiral, a black butterfly with white stripes. The Admiral primarily resides in today’s Canadian provinces and is the official insect emblem of Quebec. Further south, in what would soon become the USA, there was a yellow-orange spotted butterfly with blue, black, and brown markings, which the lepidopterists named the Red-Spotted Purple. Today, it is recognized as New York State’s butterfly.
Neither insect’s name seems entirely accurate, but the White Admiral is true to its title in one sense: like a commando in a combat zone, it uses stealth to survive. Its black and white stripes break up its outline, making it harder for predators to target. The Red-Spotted Purple, on the other hand, wants to be seen. Its vibrant coloration mimics the wing pattern of another poisonous species, tricking predators into thinking it is too dangerous to eat.
For a while, everything remained straightforward for the lepidopterists: they had two butterflies with distinct wing patterns, different survival strategies, and largely separate territories. However, something interesting occurs near the U.S.-Canada border, where the ranges of the two insects overlap. Here, butterflies with both colorful spots and white stripes appear—similar to a combination of the Red-Spotted Purple and White Admiral. These turned out to be the unusual offspring of the two species.
This discovery led scientists to reconsider whether the Admiral and Purple had more in common than their appearances suggested. When two organisms look very different, it’s natural to classify them as different species. However, beneath their colors, these two butterflies are surprisingly similar—genetically, anatomically, and behaviorally. In fact, they mate with each other in the wild just as readily as they do with their own species.
All these factors eventually convinced scientists to classify the two butterflies together as one species. And it’s not just butterflies whose appearances can be misleading—many other cross-border species exhibit similar complexities.

Butterflies – Insects with large, often brightly colored wings, and a fluttering flight – Butterflies are important pollinators in many ecosystems, helping plants reproduce by transferring pollen.
Species – A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding – The monarch butterfly is a well-known species that migrates long distances each year.
Lepidopterists – Scientists who study butterflies and moths – Lepidopterists often conduct field research to understand the life cycles and behaviors of different butterfly species.
Survival – The ability to continue living or existing, often despite difficult conditions – The survival of butterflies can be threatened by habitat loss and climate change.
Habitats – The natural environments where an organism lives and grows – Butterflies thrive in diverse habitats, including meadows, forests, and gardens.
Genetics – The study of heredity and the variation of inherited characteristics – Genetics play a crucial role in determining the wing patterns and colors of butterflies.
Anatomy – The branch of science concerned with the bodily structure of organisms – Understanding the anatomy of butterflies helps scientists learn how they fly and feed.
Behavior – The actions or reactions of an organism in response to external or internal stimuli – The migratory behavior of monarch butterflies is a fascinating subject for scientists.
