The Giant Swallowtail (Papilio cresphontes) is the largest butterfly in North America, with a wingspan that can reach up to 6 inches! Its striking black-and-yellow pattern and long "tails" on its hindwings make it a standout in the butterfly world. What’s really interesting about this species is its caterpillar, often called the "orange dog" by citrus farmers. The caterpillars feed on the leaves of citrus trees, and their unique brown-and-white coloring makes them look like bird droppings—a clever disguise to avoid predators.

The Zebra Longwing butterfly (Heliconius charithonia) has a pretty unique diet compared to most butterflies! While many butterflies only sip nectar from flowers, Zebra Longwings can also eat pollen. They collect pollen with their proboscis (their long, straw-like mouthpart) and mix it with saliva to create a protein-rich "smoothie." This extra protein helps them live much longer than other butterflies—up to several months!

The Pipevine Swallowtail (Battus philenor) is a striking butterfly with iridescent blue or blue-green wings and striking orange spots on the underside. What makes this butterfly truly fascinating is its connection to the pipevine plant (Aristolochia), which is toxic to most animals. The caterpillars feed exclusively on pipevine leaves, absorbing the plant’s toxins, which make both the caterpillars and adult butterflies poisonous to predators. This toxicity gives them a bold defense mechanism, and their bright colors serve as a warning to predators to stay away.

The Viceroy butterfly (Limenitis archippus) is a master of disguise and has a fascinating survival strategy! It looks almost identical to the Monarch butterfly, which is famous for being toxic to predators because of the milkweed it eats as a caterpillar. This look-alike trick is called mimicry. Predators, like birds, avoid the Viceroy because they mistake it for the bad-tasting Monarch.
Identify the The Great Spangled Fritillary (Speyeria cybele) is a large, eye-catching butterfly known for its vibrant orange wings adorned with black stripes and silvery-white spots on the underside. These butterflies are commonly found in open fields, meadows, and gardens, where they feed on the nectar of flowers like milkweed, thistles, and coneflowers. What makes them particularly interesting is their close relationship with violets—their caterpillars rely exclusively on violet plants for food. The females lay eggs near violet plants in late summer, and the caterpillars hatch, overwinter, and emerge in spring to continue the cycle.Butterfly!

The California Sister (Adelpha californica) is a striking butterfly known for its bold black, white, and orange markings. It gets its name from the white bands on its wings, which are said to resemble a nun’s habit. This butterfly is commonly found in oak woodlands and forests along the West Coast, particularly in California. What makes the California Sister unique is its close relationship with oak trees—its caterpillars feed exclusively on oak leaves, while adults are often seen perched on or near oak trees. They also have a feisty side: adults are known to aggressively defend their territory, chasing away other butterflies and even birds.

The Tiger Swallowtail butterfly (Papilio glaucus) is one of the most recognizable butterflies in North America, thanks to its bold black stripes on a bright yellow background, resembling a tiger's pattern. Here’s something cool about them: they have a special trick to avoid predators. When they’re resting, their wings look like leaves, helping them blend into their surroundings. But if a predator gets too close, they can suddenly reveal their bright colors, which can startle the predator and give the butterfly a chance to escape.

The Red-Spotted Purple butterfly (Limenitis arthemis astyanax) is a stunning butterfly known for its deep blue or black wings with iridescent shimmering patches and bright red-orange spots along the edges. What makes this butterfly especially interesting is its clever survival strategy: it mimics the appearance of the poisonous Pipevine Swallowtail butterfly. This mimicry, called Batesian mimicry, helps protect the Red-Spotted Purple from predators, even though it isn’t toxic itself. These butterflies are often found in woodlands, gardens, and near streams, where they feed on tree sap, rotting fruit, and occasionally flower nectar.

The Northern Pearly-Eye butterfly (Enodia anthedon) is a subtle yet fascinating butterfly often found in shady woodlands and near streams. Unlike many butterflies that prefer sunny open spaces, the Northern Pearly-Eye thrives in darker, forested areas. Its wings are a soft brown with delicate, eye-like spots called ocelli, which can help confuse predators. These butterflies are also known for their unique behavior—they often land on tree trunks or the forest floor, blending in perfectly with their surroundings. They feed on tree sap, rotting fruit, and occasionally flower nectar.

The Buckeye butterfly (Junonia coenia) is a striking and resilient butterfly known for its eye-catching wing patterns. Its wings feature bold eyespots, which help scare off predators by making them think a larger animal is watching. Buckeyes are tough little butterflies—they can be found across much of the United States, even in harsh environments, because they adapt well to different habitats like fields, gardens, and roadsides.

The Monarch butterfly (Danaus plexippus) is famous for its incredible 3,000-mile migration from Canada and the U.S. to Mexico, a journey completed over multiple generations. Monarch caterpillars feed exclusively on milkweed, which makes them toxic to predators, and their bright orange and black colors serve as a warning to stay away. Sadly, habitat loss and the decline of milkweed have put Monarchs at risk, making conservation efforts crucial to protect these amazing butterflies and their epic migration.

The Zebra Swallowtail butterfly has a really cool connection to the pawpaw tree! Its caterpillars only eat the leaves of pawpaw trees, which contain chemicals that are toxic to most animals. These chemicals make the caterpillars—and later, the adult butterflies—taste bad to predators like birds, helping keep them safe. This means the Zebra Swallowtail’s survival depends on having pawpaw trees around, making their relationship really special!
