Moths in North Carolina

In North Carolina, the moths most likely on the wing depend heavily on the month, but a few headliners show up again and again in the open records. The pale green Luna Moth (Actias luna) is one of the state's most-recorded large moths from spring into early fall, while the big rust-and-yellow Imperial Moth (Eacles imperialis) surges in July and August. The orange-and-gray Ailanthus Webworm Moth (Atteva punctella) is among the most-reported moths of high summer, and the Rosy Maple Moth (Dryocampa rubicunda), in its sherbet pink and yellow, runs strong from April through August. Earlier in spring, the Eastern Tent Caterpillar Moth (Malacosoma americana) dominates April records, and by fall the Fall Webworm (Hyphantria cunea) and the fuzzy Isabella Tiger Moth (Pyrrharctia isabella), whose larva is the famous woolly bear, take over. You'll also find day-flying hawkmoths like the Snowberry Clearwing (Hemaris diffinis), plus the Io Moth (Automeris io) and overwintering-brood Polyphemus Moth (Antheraea polyphemus). These are the species most often recorded in open GBIF data across roughly North Carolina, so think of it as "most likely," not a complete checklist.

Which moths peak in spring versus summer versus fall in North Carolina?

North Carolina's moth lineup turns over noticeably across the season, and the per-month records make the shifts easy to read.

Early spring (March-April) belongs to the loopers and tent caterpillars. Phoberia atomaris tops the March records, alongside the Tulip-tree Beauty (Epimecis hortaria), Cissusa spadix, and the Eastern Tent Caterpillar Moth (Malacosoma americana). That last species explodes in April, where it is by far the most-recorded moth in the state (its springtime caterpillar tents in cherry and crabapple are a giveaway). April is also when the Luna Moth (Actias luna) climbs into the top of the list, joined by the Forest Tent Caterpillar Moth (Malacosoma disstria), the White-marked Tussock Moth (Orgyia leucostigma), and the first strong showing of the Rosy Maple Moth (Dryocampa rubicunda).

Late spring (May-June) is when the giant silkmoths and hawkmoths really arrive. May records are led by the smoky day-flying Malthaca dimidiata and still-heavy tent caterpillars, but Luna, the Tuliptree Silkmoth (Callosamia angulifera), and the Polyphemus Moth (Antheraea polyphemus) are all among the most-reported. June brings the Io Moth (Automeris io) into the list and keeps Luna, Rosy Maple, and the Snowberry Clearwing hawkmoth (Hemaris diffinis) flying, along with the orange Ailanthus Webworm Moth (Atteva punctella) and the Painted Lichen Moth (Hypoprepia fucosa).

Mid-summer (July-August) is peak silkmoth season. July records are headed by Ailanthus Webworm and the Imperial Moth (Eacles imperialis), with Luna, Rosy Maple, and the Banded Tussock Moth (Halysidota tessellaris) close behind. August looks similar, with Ailanthus Webworm, Luna, Snowberry Clearwing, and Imperial all heavily recorded, plus the Fall Webworm (Hyphantria cunea) building toward its autumn peak.

Fall (September-October) swings toward the tiger moths and webworms. September is dominated by Fall Webworm, the Banded Tussock Moth, and the Virginian Tiger Moth (Spilosoma virginica), with the American Dagger Moth (Acronicta americana) and a late flush of Polyphemus also showing up. October records are led by the Isabella Tiger Moth (Pyrrharctia isabella) - the woolly-bear moth - along with the Yellow-collared Scape Moth (Cisseps fulvicollis) and the striking black-spotted-white Giant Leopard Moth (Hypercompe scribonia).

What moths fly in winter in North Carolina?

North Carolina has a genuine winter moth fauna, which is part of what makes mothing here rewarding year-round. December through February records are dominated by cold-hardy Geometridae: Phigalia denticulata, Phigalia strigataria, the Fall Cankerworm (Alsophila pometaria), and Iridopsis defectaria, along with the ever-present Green Cloverworm (Hypena scabra). Even in the dead of winter, the occasional Polyphemus Moth turns up in the records, and the Bagworm Moth (Thyridopteryx ephemeraeformis) lingers. So a mild January night near a porch light in the Piedmont or coastal plain is rarely a wasted one.

Which charismatic moths should I watch for in North Carolina?

If you're hoping for the showstoppers, the data points to a clear set:

• Luna Moth (Actias luna) - the long-tailed pale green silkmoth, recorded from March into September and near the top of the list for most of that span.
• Imperial Moth (Eacles imperialis) - large, yellow blotched with rosy purple; a July-August signature species here.
• Io Moth (Automeris io) - yellow with dramatic eyespots, appearing in the June records.
• Polyphemus Moth (Antheraea polyphemus) - big tan silkmoth with hindwing eyespots, recorded across the cold months and peaking in May.
• Rosy Maple Moth (Dryocampa rubicunda) - small, unmistakable pink-and-yellow, abundant April through August.
• Snowberry Clearwing (Hemaris diffinis) - a bumblebee-mimic hawkmoth that flies by day, common April to September.
• Giant Leopard Moth (Hypercompe scribonia) - bright white with bold black rings, in the fall records.

You'll notice some famous giant silkmoths aren't among North Carolina's most-recorded names - cecropia, for instance, doesn't crack these lists - which is exactly why the data matters more than reputation when you're deciding what to expect tonight.

How complete is this North Carolina list?

This is the set of moths most often recorded in open, openly licensed GBIF observations across an approximate North Carolina area - essentially the species people log and share most. It is a "most-recorded / most likely" picture, not an exhaustive state checklist. North Carolina almost certainly hosts well over 2,000 moth species across its mountains, Piedmont, and coastal plain, and many rarer or harder-to-photograph ones never make a most-recorded list. We're a forecast-and-discovery tool, not an identifier: if you've photographed something and want a confirmed ID, iNaturalist and the Moth Photographers Group / Leps resources are the right next stop.

How do I get tonight's personalized North Carolina moth list?

The lists above are statewide and monthly. To get the species most likely at your exact spot tonight, enter your location and the tool pulls the nearby, in-season most-recorded moths for that date - so a coastal night in September reads differently from a mountain night in June. You'll also get a "good mothing night" score that blends local weather and the moon phase (warm, still, humid, dark nights generally beat cold, windy, bright-moon ones) so you can decide whether to set up a sheet and light tonight or wait for a better one.
