21 Types of Moths in New Jersey: From Luna Moths to Common Pantry Pests
October 6, 2026
Step outside on a warm Garden State evening and switch on a porch light, and within minutes something will show up fluttering around the bulb. New Jersey is home to an extraordinary range of moths, and most residents never learn to tell one from another beyond “the big green one” or “the thing eating my sweaters.” According to the New Jersey Butterfly Club,
there may be 1500 or more species of moths in NJ, compared to about 125 species of butterflies, which means the state’s moth fauna dwarfs its more famous daytime cousins. This guide narrows that overwhelming number down to 21 species you’re actually likely to encounter, from giant silk moths the size of a small bird to the tiny pantry invaders raiding your kitchen cabinets. Each entry covers what the moth looks like, where it turns up in New Jersey, and what makes it worth a second look.
Key Insight: The easiest way to separate a moth from a butterfly at a glance is the antennae. Butterflies have slender antennae with a clubbed tip, while moths have tapered, feathery, or saw-edged antennae built to detect pheromones in the dark.
1. Luna Moth
The luna moth (Actias luna) is arguably New Jersey’s most recognizable moth, and the New Jersey Division of Fish and Wildlife doesn’t hold back its praise. The luna moth has been called the most beautiful insect in North America. Its pale green wings stretch into two long, curving tails, with a thin band of pink or yellow tracing the wing edges and transparent eyespots on each wing.
Adults have no functional mouthparts, so they never eat as adults; they survive on energy stored from their caterpillar stage and typically live only about a week. The trailing tails aren’t just decorative — they spin during flight, disrupting the echolocation of hunting bats. Look for luna moths near birch, sweetgum, and hickory trees, their preferred host plants, from late spring through summer.
2. Io Moth
The io moth (Automeris io) belongs to the same giant silk moth family as the luna, but it trades subtlety for shock value. Males fly with bright yellow wings, while females wear a deeper reddish-brown, and both sexes reveal a pair of large blue-black eyespots ringed in white the instant the forewings snap open. That eyespot flash is a defense mechanism meant to startle birds and other predators long enough for the moth to escape.
Io moth caterpillars are just as memorable, covered in clusters of branching spines that deliver a genuine sting if touched. If you spot a lime-green, spiny caterpillar on shrubs like willow, cherry, or corn in a New Jersey backyard, it’s worth admiring from a distance rather than picking up.
3. Cecropia Moth
North America’s largest native moth calls New Jersey home. According to Precision Tree and Landscape, this species is known for shades of brown and large eyespots that add to its prominence as North America’s largest native moth, typically 4.3 to 5.9 inches across. That description matches the cecropia moth (Hyalophora cecropia), whose reddish-brown body and dusky wings are banded with white and marked with crescent-shaped eyespots.
Cecropia caterpillars grow to match their adult size, reaching nearly four inches long with rows of blue, yellow, and red tubercles down a bluish-green body. They feed on maple, cherry, and birch leaves, and their large brown cocoons are often spotted clinging to bare branches through winter, long after the caterpillar inside has pupated. For a broader look at how this species compares to moths elsewhere, the moths found in Florida include several relatives from the same silk moth family.
4. Pandora Sphinx Moth
The pandora sphinx moth (Eumorpha pandorus) is one of the giant-bodied sphinx moths that share New Jersey’s night skies with the silk moths. Missouri Department of Conservation field notes describe the family well: sphinx moths are usually large and heavy-bodied with a long, pointed abdomen, and members of the family often hover near flowers, feeding on nectar and looking like hummingbirds or bumblebees.
The pandora sphinx fits that mold with olive-green forewings patterned in pink and cream, giving it a mottled, almost camouflaged look against tree bark. Its caterpillars feed heavily on grape and Virginia creeper vines, sometimes growing large enough that gardeners mistake them for something more exotic. Adults are most active at dusk from midsummer into early fall.
5. Hummingbird Clearwing Moth
Few New Jersey moths cause as much daytime confusion as the hummingbird clearwing (Hemaris thysbe). Unlike most moths on this list, it flies in broad daylight, hovering at flowers with a blur of wings that genuinely resembles a hummingbird or a fat bumblebee. Its wings are largely transparent with reddish-brown borders, and its stout, fuzzy body ranges from olive-green to burgundy.
This species is often lumped in with other insects that look like bees, since its hovering flight and rounded body throw off casual observers at first glance. Gardeners who plant bee balm, phlox, or verbena for the bees of New Jersey often find hummingbird clearwings sharing the same flower beds, feeding side by side with true pollinators.
6. Large Hypenodes Moth
Far less flashy than the silk moths and sphinxes, the large hypenodes moth represents the huge, under-documented middle of New Jersey’s moth fauna. Moth Identification groups it among the state’s notable species, noting that the large hypenodes moth belongs to the Erebidae family, the largest moth family in North America by species count.
This small, brownish moth is easy to overlook against tree bark or leaf litter, which is exactly the point of its coloring. Erebid moths like this one make up a huge share of the “mystery moths” that show up at porch lights and get photographed for identification apps without ever being named. Its presence in New Jersey is a reminder that the showy giant silk moths are the exception, not the rule.
7. American Ermine Moth
The American ermine moth (Yponomeuta multipunctella) earns its name from a wing pattern that resembles the white winter coat of an ermine, dotted with fine black spots across a wingspan of roughly 1.1 to 1.3 inches. It’s a small moth, but its bold contrast makes it stand out against green foliage far more than its size would suggest.
Larvae of this species feed on a wide range of hardwood trees, including oak, elm, maple, cherry, apple, and poplar, often spinning loose communal webbing over leaf clusters while they feed. Adults emerge in summer and are known for a distinctly strong scent, an unusual trait among New Jersey’s smaller moths. As adults, they switch to nectar, making them minor but genuine pollinators in the same neighborhoods where their larvae once fed on shade trees.
8. Arcigera Flower Moth
The arcigera flower moth (Schinia arcigera) is a small, richly patterned noctuid moth in warm shades of orange, brown, and cream that blend almost perfectly with the flower heads it visits. It belongs to a genus of “flower moths” whose caterpillars develop inside the seed heads of their host plants rather than chewing exposed leaves.
This species is closely tied to aster plants, where the larvae feed on developing seeds within the flower structure itself, camouflaged from most predators. Because it depends on a fairly specific set of native asters, sightings tend to cluster around meadows, roadside edges, and unmowed fields rather than manicured lawns or gardens. Habitat loss from mowing and development is a real pressure on flower moths like this one across the Northeast.
9. White-lined Sphinx Moth
The white-lined sphinx moth (Hyles lineata) is one of the most widespread sphinx moths in North America, and New Jersey sees regular sightings of it at dusk and even during the day. Its brown forewings are crossed by a bold white stripe from base to tip, with a series of pale streaks radiating outward, while its hindwings flash rose-pink bordered in black.
Like the hummingbird clearwing, this species hovers at flowers to feed, and its rapid wingbeats and stocky body regularly get mistaken for actual hummingbirds by first-time observers. It’s a generalist feeder as a caterpillar, tolerating everything from garden petunias to wild four-o’clocks, which helps explain why it turns up in such a wide range of New Jersey habitats, from coastal dunes to suburban flower beds.
Pro Tip: If you want to attract silk moths and sphinx moths for identification photos, try a simple sugar-and-fruit bait painted on a tree trunk at dusk, or leave an outdoor light running near a white sheet. Both techniques draw moths in without needing a specialized mothing trap.
10. Polyphemus Moth
The polyphemus moth (Antheraea polyphemus) is named for the one-eyed giant of Greek myth, and it’s easy to see why once you spot the huge, staring eyespot on each hindwing. As Bird Watching HQ describes it, polyphemus moths are easily recognized for their large, stunning eyespots, and while people find the pattern beautiful, predators find it frightening because it resembles the face of a great horned owl, which helps distract and startle attackers.
You can find polyphemus moths across New Jersey in forests, orchards, wetlands, and even urban parks wherever oak, maple, or birch trees grow nearby. Despite their striking size, adults have an extremely short lifespan, living only about four days, and they emerge from the cocoon with no mouth at all, entirely focused on finding a mate before time runs out.
11. Fall Webworm Moth
The fall webworm moth (Hyphantria cunea) is a plain, satiny white moth that most New Jersey residents never actually notice as an adult. What they do notice is the caterpillar’s handiwork: loose, messy silk webs that appear at the tips of tree branches in late summer. According to a Bug Identifier field guide, adults have satiny white wings, sometimes with small black or brown speckles, a stout hairy white-to-orange body, and a wingspan of roughly 1.2 to 1.7 inches.
Unlike the similarly web-building eastern tent caterpillar, the fall webworm constructs its web at branch tips later in the growing season, gradually enclosing more foliage as the colony grows. Homeowners often panic at the sight of a large web engulfing an entire branch, but damage is nearly always cosmetic, limited to leaves inside the enclosure rather than the whole tree.
12. Southern Flannel Moth
The southern flannel moth (Megalopyge opercularis) looks harmless as an adult, covered in soft, fur-like scales in shades of golden-orange to pale cream. A-Z Animals notes that adult wingspan is typically 25 to 36 millimeters, and the species is best known for its larva, the “puss caterpillar,” which is covered in dense, fur-like setae hiding venomous spines that can cause painful stings in humans.
Important Note: The puss caterpillar looks like a small tuft of fur or a tiny toupee, but its hidden spines can deliver a sting severe enough to require medical attention in sensitive individuals. Never handle a fuzzy caterpillar with bare hands, and teach children to admire New Jersey caterpillars with their eyes only. This is general safety information, not medical advice; consult a healthcare provider for any reaction to a caterpillar sting.
13. Azalea Sphinx Moth
The azalea sphinx moth (Darapsa choerilus) is a medium-sized sphinx moth with mottled brown and olive forewings that blend easily into bark and leaf litter. Its hindwings show a flash of pale orange near the base, visible mainly when the moth is disturbed and briefly spreads its wings.
True to its name, this species’ caterpillars favor azalea and viburnum shrubs common in New Jersey landscaping, along with wild honeysuckle in woodland edges. Because azaleas are so widely planted around homes across the state, this sphinx moth turns up in suburban yards nearly as often as in forests, making it one of the more accessible sphinx moths for backyard observers to find.
14. Small-eyed Sphinx Moth
The small-eyed sphinx moth (Paonias myops) gets its name from a modest blue-and-black eyespot tucked on each hindwing, far smaller and less dramatic than the eyespots of the io or polyphemus moth. Its forewings are mottled brown and gray, scalloped along the edge in a way that helps it disappear against tree bark when at rest.
Caterpillars feed primarily on cherry, apple, and other members of the rose family that grow throughout New Jersey’s orchards and hedgerows. Adults are strictly nocturnal and rarely visit flowers, spending their short lives instead searching for mates, which makes them a species most New Jersey residents encounter only when one lands near a porch light.
15. Rose Hooktip Moth
The rose hooktip moth (Oreta rosea) stands out among New Jersey’s smaller moths thanks to a distinctly hooked tip on each forewing, a shape shared by the small family of hooktip moths. Its wings are a soft pinkish-tan, sometimes with a faint rosy flush that gives the species its common name.
Despite the name, its caterpillars don’t feed on roses; they favor birch, ironwood, and other trees in the birch family instead. This moth is most active from late spring through summer, and its resting posture — wings held flat with that hooked tip raised — makes it one of the easier small moths to identify once you know what to look for.
16. Webbing Clothes Moth
Few New Jersey moths generate as many frustrated phone calls to pest control as the webbing clothes moth (Tineola bisselliella). This small, golden-tan moth rarely flies far or fast, preferring to scurry into dark closets and drawers rather than toward light. Viking Pest Control, a New Jersey pest management company, notes that moths infesting homes and businesses in the state include the webbing and casemaking clothes moths, along with the Mediterranean flour moth.
Its larvae, not the adults, cause the damage most people notice: irregular holes chewed into wool sweaters, carpets, and other natural-fiber fabrics stored in dark, undisturbed spaces. Because they avoid light, infestations often go undetected for months until a favorite sweater turns up full of holes.
17. Casemaking Clothes Moth
The casemaking clothes moth (Tinea pellionella) is the webbing clothes moth’s close cousin, and the two are frequently confused by homeowners dealing with fabric damage. The key difference is behavioral: casemaking clothes moth larvae spin a small silk case around themselves as they feed, dragging this portable shelter along wherever they crawl.
That case, often camouflaged with bits of the fabric the larva has eaten, is one of the clearest signs distinguishing this species from its webbing relative. Both species share a similar tan-brown coloring as adults and a preference for wool, fur, feathers, and other keratin-based materials found in closets throughout New Jersey homes.
Common Mistake: Many homeowners assume any small brown moth found near stored food or fabric is the same species. Clothes moths target closets and wool, while pantry moths like the Mediterranean flour moth stick to grain, flour, and cereal — treating one problem with the wrong method rarely solves the other.
18. Mediterranean Flour Moth
The Mediterranean flour moth (Ephestia kuehniella) is New Jersey’s most common pantry invader, a small gray moth with faint dark zigzag markings across its forewings. Unlike clothes moths, this species targets stored grain products: flour, cereal, pasta, and dried pet food are all common sources of an infestation that started at a food processing or storage facility before ever reaching a home kitchen.
Larvae spin silk threads through infested food, clumping it together in a way that’s often the first visible sign of trouble. Because this species reproduces quickly indoors year-round, unlike New Jersey’s outdoor moths tied to specific seasons, an infestation can spread through an entire pantry within a few generations if the source isn’t identified and discarded.
19. Angoumois Grain Moth
The Angoumois grain moth (Sitotroga cerealella) is a tiny, pale tan moth with narrow, pointed wings fringed in fine hairs, easily mistaken for lint drifting through a kitchen. Despite its unassuming looks, it’s a serious agricultural pest that targets whole grain kernels rather than processed flour.
Larvae bore directly into individual kernels of corn, wheat, rice, or other stored grains, developing entirely inside a single seed before emerging as adults. This makes infestations especially hard to spot early, since the damage is hidden inside the grain itself until the kernel is broken open or the adult moth chews its way out.
20. Pug Moth
New Jersey hosts dozens of pug moth species, all belonging to the genus Eupithecia, a group so large and visually similar that even experienced lepidopterists rely on genital dissection to separate some species with certainty. InsectIdentification.org lists the pug moth under the genus Eupithecia among the state’s documented moth species.
Pug moths are small, typically gray or brown, with a resting posture that holds the wings flat and slightly forward, giving them a distinctive triangular silhouette against bark or leaves. Their caterpillars feed on an enormous range of host plants depending on species, and because so many pugs look nearly identical, casual observers usually just note “a pug moth” rather than attempting species-level identification in the field.
21. Grass-Veneer Moth
Grass-veneer moths, in the genus Agriphila, are the small tan and brown moths that explode out of New Jersey lawns in waves whenever you walk across grass on a summer evening. InsectIdentification.org’s New Jersey species list includes the grass-veneer moth under the genus Agriphila as one of the state’s documented Crambidae.
At rest, grass-veneer moths roll their narrow wings tightly around their body, creating a thin, cylindrical shape that helps them blend into grass blades and thatch. Their caterpillars feed on grass roots and stems, and while a few individuals in a lawn cause no noticeable harm, larger populations are sometimes associated with patchy, thinning turf in home lawns and golf courses across the state.
| Common Name | Typical Wingspan | When You’ll See It |
|---|---|---|
| Luna Moth | 3–4.5 inches | Late spring to summer |
| Cecropia Moth | 4.3–5.9 inches | Late spring to early summer |
| Polyphemus Moth | 4–6 inches | Spring to midsummer |
| Southern Flannel Moth | 1–1.5 inches | Spring through fall |
| Fall Webworm Moth | 1.2–1.7 inches | Adult in early summer; webs in late summer |
| Webbing Clothes Moth | Under 0.5 inch | Year-round indoors |
New Jersey’s moths range from palm-sized giants that live for only a week to grain-bin invaders that persist indoors all year, and that diversity is exactly what makes the state’s insect life worth a closer look after dark. Whether you’re trying to identify what’s chewing your sweaters or what just landed on your porch screen the size of a small bird, the species above cover the ones you’re most likely to actually run into.
For a wider view of what shares the landscape with these moths, guides to New Jersey’s spiders, ants, and insects more broadly round out the picture of who’s active in the Garden State once the sun goes down.
If this list only scratched the surface, the deeper roundup of New Jersey moth species and the broader catalog of moth types found across North America are good next stops. Curious how New Jersey’s numbers stack up against neighboring states? Comparable guides to the moths of Georgia and Texas, along with a look at how many moth species exist worldwide, put the Garden State’s 1,500-plus species into perspective. And if you’re near the New York border, the insects of New York share many of the same species covered here, since moths rarely stop for state lines.
