20 Types of Butterflies in Indiana: A Backyard Identification Guide
October 20, 2026
Indiana sits at a crossroads of prairie, forest, and wetland habitat, and that mix supports a surprising range of butterflies for a Midwestern state. Gardeners, hikers, and backyard birdwatchers who start paying attention to the types of butterflies in Indiana quickly notice patterns: a wave of monarchs in late summer, clouds of small white and yellow wings over clover fields, and the occasional tropical stray that wandered far north of its usual range.
Indiana’s official state insect is actually Say’s firefly, not a butterfly, so the butterflies covered here earn their reputation the old-fashioned way — through sheer visibility and variety. This guide walks through 20 species a person is likely to encounter across the state, grouped loosely by family, with identification cues, host plants, and the habitats where each one turns up most often.
1. Monarch
The monarch (Danaus plexippus) is the butterfly most Hoosiers can identify on sight, with its burnt-orange wings crossed by heavy black veins and a black border dotted with white spots. Butterflies and Moths of North America notes that Monarchs stop to feed on flower nectar and to roost together at night during migration, which is why a single stand of goldenrod or zinnias can attract dozens at once in September.
Monarchs depend entirely on milkweed as a caterpillar host plant, and that narrow diet is tied directly to their famous migration. According to the Monarch Joint Venture, Wendy Caldwell has observed that monarchs typically arrive between mid-May and early June, and are present throughout the summer in Indiana. They remain visible across the state all summer until migrating south from late August through November.
The species carries real conservation weight. Animal Diversity Web reports that the annual monarch migration is considered a “threatened phenomena” by the International Union for Conservation of Nature, and researchers have documented significant declines in monarch numbers over the past few decades. Anyone curious how the monarch compares to other migratory species across the continent can check this overview of butterflies found throughout North America.
Important Note: Monarch populations fluctuate year to year based on weather, milkweed availability, and conditions at their Mexican overwintering sites. Planting native milkweed species rather than tropical varieties helps support healthy migration timing.
2. Viceroy
At a glance, the viceroy (Limenitis archippus) looks like a smaller monarch, and that resemblance is the entire point. Wikipedia’s entry on the species explains that it was long thought to be a Batesian mimic of the monarch, but since the viceroy is also distasteful to predators, it is instead considered a Müllerian mimic — meaning both species benefit from sharing a warning pattern rather than one simply copying the other.
The giveaway feature is a black line that cuts straight across the hindwing, something monarchs never show. Butterflies and Moths of North America lists the flight period as two to three broods from May through September across most of its range, so viceroys overlap with monarchs for most of the Indiana butterfly season.
Viceroy caterpillars feed on willows, poplars, and cottonwoods, which puts the species squarely in wet habitats. Carolina Nature’s field notes confirm the pattern seen across its range, describing viceroys as fairly common in wet habitats where willows, their host plants, grow. Streambanks, pond edges, and swampy woodlots across the state are reliable places to look. For a sense of how the surrounding region compares, this guide to insects found in neighboring Ohio covers several of the same wetland species.
Pro Tip: Watch how the butterfly glides. Monarchs hold their wings in a shallow V and float lazily; viceroys hold their wings flat and fly with quicker, more erratic wingbeats.
3. Red Admiral
The red admiral (Vanessa atalanta) is unmistakable once seen up close: velvety black wings crossed by bold orange-red bands, with white spots near the wingtips. Unlike many nectar specialists, red admirals have a well-earned reputation for visiting overripe or fermenting fruit, and gardeners sometimes attract them by leaving cut, overripe fruit in a sunny spot.
Red admirals are true migrants, moving south in fall and returning north again as temperatures warm. Caterpillars feed almost exclusively on plants in the nettle family, so a patch of stinging nettle at the edge of a yard or woodlot is often a nursery for the next generation rather than a nuisance weed. Indiana’s mix of forest edges and overgrown fencerows gives this species plenty of room to thrive, much like the related species covered in this roundup of butterflies found in North Carolina.
4. Painted Lady
Few butterflies travel as far or as unpredictably as the painted lady (Vanessa cardui), often cited as the most widely distributed butterfly species on Earth. Its mottled orange, black, and white wings look similar to the red admiral at a distance but lack the admiral’s bold solid bands, showing a more fragmented, camouflage-like pattern instead.
Painted ladies are generalists both in diet and habitat. Caterpillars feed on thistle, mallow, and a wide range of other weedy plants, and adults turn up everywhere from open prairie remnants to suburban flowerbeds. Some years bring enormous irruptions of painted ladies moving through the Midwest in numbers that rival monarch flights, while other years the species is scarce — a volatility also documented in states further west, including this look at butterfly species found in Colorado.
5. Falcate Orangetip
One of the earliest butterflies to appear each spring in Indiana, the falcate orangetip (Anthocharis midea) gets its name from the hooked, or falcate, wingtip and the small orange patch found only on males. Females lack the orange mark entirely, showing plain white wings with faint gray-green marbling on the underside.
This species flies for just a few weeks, timed to coincide with the blooming of rock cress and other small mustard-family wildflowers that serve as host plants. Once those ephemeral blooms fade, the falcate orangetip disappears for the year, overwintering as a chrysalis until the following spring. Its brief appearance places it among a broader group of short-lived spring fliers detailed in this overview of different types of insects and their life-cycle timing.
6. Olympia Marble
The Olympia marble (Euchloe olympia) is a small, pale butterfly best identified by the delicate olive-green marbling on the underside of its hindwings, which gives the species its common name. Upperwings are mostly plain white with light gray along the edges, making this one easy to overlook against pale spring wildflowers.
In Indiana, the Olympia marble favors dry, sandy habitats such as prairie remnants, dune country near Lake Michigan, and limestone barrens, where its host plants in the mustard family grow in open, sun-baked soil. Like the falcate orangetip, it flies for only a short window in early spring. Dry prairie specialists like this one share habitat requirements with several species found well north of Indiana’s borders, as outlined in this guide to insects native to Canada.
7. Mustard White
The mustard white (Pieris oleracea) is a native woodland butterfly, plain white above with only faint gray veining visible on the underside in spring broods. It is easy to confuse with the far more common cabbage white, but the mustard white tends to stick closer to forest edges and rich, moist woodlands rather than open gardens.
Toothwort and other native spring mustards serve as the primary host plants, and that dependence on native vegetation has made the mustard white vulnerable to competition from invasive garlic mustard, which can attract egg-laying females to a plant that poisons the caterpillars that hatch on it. Populations have thinned in parts of its eastern range for this reason, a pattern echoed among native plant specialists documented in regions as far as New York’s native insect communities.
8. West Virginia White
The West Virginia white (Pieris virginiensis) looks similar to the mustard white but shows slightly translucent, veiny wings and a stronger preference for mature, undisturbed forest. It is considered one of Indiana’s more sensitive butterfly species, limited to pockets of old-growth or old-growth-adjacent woodland in the southern part of the state.
Toothwort is again the essential host plant, and the same garlic mustard problem that threatens the mustard white hits this species even harder, since West Virginia whites are more tightly tied to intact forest understory. Habitat fragmentation and invasive plants have pushed this butterfly toward rarity across much of its historic range. Indiana’s remaining forest tracts that support the species also shelter other forest specialists, including the bat species found across Indiana.
Key Insight: Garlic mustard acts as an ecological trap for native white butterflies. Females recognize it as a mustard-family host plant and lay eggs on it, but the caterpillars that hatch cannot survive on the chemicals it produces.
9. Cabbage White
The cabbage white (Pieris rapae) is almost certainly the most common butterfly a person will see in an Indiana backyard, vegetable patch, or parking lot median. It is not native to North America; the species arrived from Europe in the 1860s near Quebec and spread across the continent within decades, and it now produces several generations per year wherever brassica-family plants grow.
Plain white wings with one or two black spots make this butterfly simple to identify, though its sheer abundance is what sets it apart from the native whites described above. Caterpillars feed on cabbage, broccoli, and related garden crops, which has earned the species a reputation among vegetable gardeners as a minor pest. Its flight overlaps with pollinator activity covered in this guide to the bee species found in Indiana.
10. Checkered White
The checkered white (Pontia protodice) earns its name from the bold black-and-white checkered pattern across its wings, heavier in females than in the more lightly marked males. It favors open, disturbed ground — roadsides, vacant lots, and dry fields — rather than the forest edges preferred by the mustard and West Virginia whites.
Host plants are again drawn from the mustard family, particularly weedy species that thrive in poor, sun-baked soil. Checkered whites have declined across parts of the eastern United States as open habitat has given way to development, though they remain more reliably found in Indiana’s drier, southern counties. The species shares its taste for disturbed, open terrain with butterflies found much farther south, including several covered in this look at insect species native to Texas.
11. Clouded Sulphur
The clouded sulphur (Colias philodice) is a pale lemon-yellow butterfly common in lawns, meadows, and clover fields throughout Indiana from spring through fall. Its wings carry a dark border and a small central spot, features shared with its close relative the orange sulphur, which makes the two species genuinely tricky to tell apart in flight.
Clover and other legumes serve as host plants, and because clover grows almost everywhere mowed grass does, clouded sulphurs are one of the easiest butterflies to find without any special habitat at all. Unlike insects that rely on venom or biting mouthparts for defense, sulphurs depend entirely on speed and camouflage to avoid predators, a contrast worth noting against this guide to insects with stingers.
12. Orange Sulphur
The orange sulphur (Colias eurytheme), sometimes called the alfalfa butterfly, shows warmer orange-yellow coloring than its clouded cousin, though the two species hybridize often enough that intermediate individuals are common. Females of both species also produce a pale white form, sometimes called “alba,” which adds another layer of identification confusion in the field.
Alfalfa and clover fields are prime habitat, and the species has become more common in Indiana as agricultural land expanded suitable host plants across the state. Multiple generations fly each year, with numbers building steadily from spring into a fall peak.
| Feature | Clouded Sulphur | Orange Sulphur |
|---|---|---|
| Wing color | Pale lemon-yellow | Warmer orange-yellow |
| Preferred host plant | White clover | Alfalfa, clover |
| Habitat | Lawns, meadows, roadsides | Hayfields, alfalfa fields |
| Identification note | Hybridizes freely with Orange Sulphur | Females show a pale “alba” form |
Pro Tip: If a sulphur looks intermediate between pale yellow and orange, it may genuinely be a hybrid rather than a misidentified individual — the two species cross regularly where their ranges overlap.
13. Southern Dogface
The southern dogface (Zerene cesonia) is named for the dark forewing pattern that, from certain angles, resembles the profile of a dog’s face complete with a dark “eye” spot. Bright yellow wings and a strong, purposeful flight make it stand out from the plainer sulphurs when one does appear.
This species is more southern in range and generally shows up in Indiana as an uncommon stray rather than a reliable resident, typically in late summer when individuals disperse northward. False indigo and other legumes serve as host plants where the species does establish locally. Finding one in an Indiana meadow is worth pausing for, since sightings tend to be sporadic rather than annual.
14. Cloudless Sulphur
The cloudless sulphur (Phoebis sennae) is large and strikingly clean lemon-yellow, lacking the dark borders and spots that mark the smaller clouded and orange sulphurs. Its size alone — noticeably bigger than Indiana’s common sulphurs — is often enough to identify it in flight.
Senna plants are the primary caterpillar host, and because senna is more abundant in the South, cloudless sulphurs are strongest migrants that push north into Indiana gardens in mid-to-late summer rather than overwintering locally. Partridge pea, a native senna relative planted in prairie restorations, has helped support more sightings of this striking migrant across the state. Large, showy sulphurs of a similar scale also appear in distant insect faunas, including those covered in this guide to butterfly species found in Madagascar.
15. Orange-Barred Sulphur
The orange-barred sulphur (Phoebis philea) is a true rarity in Indiana, a tropical species that occasionally strays far north of its normal Gulf Coast and Caribbean range. Males show a distinctive orange bar across the forewing that gives the species its name, while females are plainer yellow with scattered dark markings.
Cassia and senna shrubs are the typical host plants in its core range, none of which grow wild in Indiana, so any individual seen in the state almost certainly arrived through wind-assisted dispersal rather than local breeding. Sightings cluster in late summer and fall when southern strays are most likely to push north. The tropical origins of this wanderer parallel species found in genuinely tropical ecosystems, like those detailed in this guide to insects of the Amazon rainforest.
16. Little Yellow
The little yellow (Pyrisitia lisa) is small even by sulphur standards, with a wingspan under an inch and a half and a pale lemon color broken by a thin black wing border. It is easy to mistake for a stray moth at first glance given its diminutive size and quick, low flight close to the ground.
Partridge pea is the preferred host plant, and where that native legume is established in prairie plantings or old fields, little yellows can produce several generations in a single season. In Indiana, the species behaves more like an uncommon visitor than a guaranteed resident, appearing most reliably in the warmer southern counties. Its pale coloring stands in sharp contrast to the deeper tones covered in this guide to purple butterfly species.
17. Sleepy Orange
The sleepy orange (Abaeis nicippe) combines deep orange wings with a heavy black border, and its name comes from a small, half-closed “eye” mark on the underside rather than any particular behavior. In flight it moves briskly and low, often along field edges and dirt roads.
Senna and partridge pea serve as host plants, placing this species in open, sunny habitats similar to those favored by the little yellow and southern dogface. Sleepy oranges feed exclusively on nectar as adults, a diet that sets every butterfly on this list apart from the parasitic feeding strategies used by blood-feeding insects. Indiana records of this species increase in late summer as southern populations expand their range northward.
18. Dainty Sulphur
The dainty sulphur (Nathalis iole) holds the title of smallest sulphur butterfly in North America, with a wingspan that rarely exceeds an inch. Pale yellow wings marked with small black patches make it resemble a miniature version of the clouded sulphur, though its tiny size is usually the fastest way to tell it apart.
Caterpillars feed on asters and related weedy composite plants, and adults favor dry, disturbed open ground such as gravel roadsides and bare patches in fields. Like several other small sulphurs on this list, the dainty sulphur behaves as an occasional stray in Indiana rather than an established resident, more common in years when southern populations expand northward. Its entirely nectar-based adult diet contrasts with wood-dependent insects covered in this guide to wood-eating insect species.
Important Note: Several sulphurs on this list — Southern Dogface, Cloudless Sulphur, Orange-barred Sulphur, Little Yellow, Sleepy Orange, and Dainty Sulphur — are southern strays in Indiana rather than year-round residents. Sightings cluster in late summer and fall as populations disperse north, and numbers vary considerably from year to year.
19. White Admiral
The white admiral (Limenitis arthemis) is the northern form of a species that, farther south, appears as the dark, iridescent red-spotted purple. In Indiana, individuals in the northern part of the state often show the classic white admiral pattern — black wings crossed by a bold white band — while those farther south can show intermediate coloring where the two forms interbreed.
Birch, aspen, and willow serve as host plants, placing this species in moist northern forests and forest edges rather than open prairie. Because the white admiral and red-spotted purple represent two forms of the same species, Indiana sits in an interesting transition zone where both patterns, and hybrids between them, can turn up within the same woodland.
20. Great Spangled Fritillary
The great spangled fritillary (Speyeria cybele) is one of the largest and most conspicuous butterflies in Indiana’s summer meadows, with bright orange wings above and a dazzling row of silver spots across the underside of the hindwing. Its size and the metallic underside spotting make it unmistakable once seen well.
Violets are the sole host plant for caterpillars, which hatch in late summer, overwinter without feeding, and do not begin eating until the following spring when fresh violet leaves emerge. Adults live relatively long for a butterfly and spend much of the summer visiting milkweed, coneflower, and thistle blooms in prairie remnants and old fields. These meadow habitats also support many of the pollinators detailed in this guide to Indiana’s native bee species.
Pro Tip: Planting native violets in a garden bed gives great spangled fritillary caterpillars a place to overwinter, since the species cannot use cultivated pansies or violas as a substitute host plant.
Spotting all 20 of these species in a single season would be an ambitious goal even for an experienced observer, but each one leaves clues that make identification easier with practice: wing shape, flight style, host plant, and the time of year it appears.
Planting native milkweed, violets, and legumes in a home garden is one of the most reliable ways to attract several species from this list at once, and it supports the same wildflower communities relied on by the state’s other wildlife, from eagles patrolling Indiana’s rivers to smaller pollinators working the same blooms.
For readers who want to take the hobby further, raising caterpillars collected locally — always from host plants found in the wild, never purchased stock from outside the region — is a hands-on way to watch metamorphosis firsthand, a practice covered in more depth in this guide to keeping insects as pets. Whether the goal is a quick backyard count or a season-long tracking project, Indiana’s mix of prairie, forest, and wetland habitat keeps offering new butterflies to learn.
