Black Swallowtail Caterpillar

Multiple types of native and introduced species of wild carrots are the hosts of the Black Swallowtail Caterpillar (Papilio polyxenes).

This is a species known for living on mock bishopweed and poison hemlock among other types of herbs.

The Black Swallowtail Caterpillar is only black in its initial growth stages.

It shows white coloring alongside its base black color later to eventually become a green caterpillar with black bands and yellow dots in its grown stage.

The damages this caterpillar causes range from minimum to complete defoliation, including host flowers and leaves.

10. Eastern Tent Caterpillar

Eastern Tent Caterpillar

This species (Malacosoma americana) is named after the communal silk tents it builds on branches.

Young caterpillars work together to create this tent-like protective structure.

Eastern Tent Caterpillars live social lives at first. As many as 300 eggs can hatch at a time which means a high number of caterpillars may live on the same host.

This species has a mostly dark body with just a few contrasting characteristics.

A dorsal stripe and a few colored spots contrast its body.

This species has a white dorsal stripe and blue dots along it.

Caterpillars of this species are identified by their tent-like structure with a Southeastern orientation on host trees.

The caterpillars of the species bear some coloring resemblance to these butterflies.

They are mostly black, similar to the black color dominating the wings of the butterfly.

Black spines also cover the body of the caterpillar throughout its growth stages.

Stinging nettle is one of its hosts and one of the main reasons for Red Admiral migration.

35. Yellow Woolly Bear

Yellow Woolly Bear

This species of woolly bear caterpillar (Spilosoma virginica) has a light yellow color and a hairy body.

Yellow Woolly Bear caterpillars feed on various plants, including clover. Their damages might not be significant most months, but can be impactful at the end of the summer.

Spotted in multiple broods per year, this is a species known to only be problematic at the end of the summer.

A small number of people coming in contact with the Yellow Woolly Bear Caterpillar may show allergic skin reactions.

Once an adult, it turns into a white moth

36. Tulip-tree Silkmoth Caterpillar

Tulip-tree Silkmoth Caterpillar

Tulip trees and magnolias are the most common hosts of the Tulip-tree Silkmoth Caterpillar (Callosamia angulifera).

The species can come with a considerable impact on its host given it feeds constantly until pupation.

It stops feeding once it turns into an adult Tulip-tree Silkmoth.

2 broods are specific to the species in North Carolina.

The first brood appears up until April while the second brood makes its appearance at the end of the summer in August.

37. Gray Hairstreak Caterpillar

Gray Hairstreak Caterpillar

Gray Hairstreak Caterpillars (Strymon melinus) are present in almost all states, including North Carolina.

The species has a typical green color, specific to most caterpillars in the state.

It feeds on many types of host plants including mallows and other types of pea plants.

The complete list of Gray Hairstreak Caterpillars is longer year on year since the species is seen eating tens of species of plants.

Legumes are also consumed by this species. The economic impact of the caterpillars is reduced compared to other pest caterpillars.

Adults also feed but prefer milkweed and other herbs.

38. Yellow-striped Armyworm

Yellow-striped Armyworm

Unlike the Gray Hairstreak Caterpillar, the Yellow-striped Armyworm Caterpillar (Spodoptera ornithogalli) is seen as a major pest on North Carolina crops and in greenhouses.

It’s here that the species feeds on corn, beet, cabbage, lettuce, potatoes, peas, and different types of melons.

Even other types of crops such as soy and cotton may be impacted by this species.

Management techniques including chemical use and encouraging parasitoid wasps in the area are often necessary.

This species has a mostly dark brown body with yellow, black, and white dorsal stripes.

Its prolegs tend to have a brighter brown color compared to the dark brown color of its body.

39. Forest Tent Caterpillar

Forest Tent Caterpillar

Forest Tent Caterpillars (Malacosoma disstria) are also damaging to the ecosystem, even if not to crops such as The Yellow Striped Armyworm.

Forest Tent Caterpillars impact trees. They feed and affect oak, aspen, and sugar maple, among other tree species.

Most times, the damages caused by hungry-feeding Forest Tent Caterpillars are manageable for trees that easily regenerate lost leaves.

Outbreaks are the ones to worry about when it comes to Forest Tent Caterpillars.

An outbreak of this species can last up to 3 years and it occurs at least once per decade.

40. Palamedes Swallowtail Caterpillar

Papilio palamedes

Red bay is one of the most impacted species when it comes to the Palamedes Swallowtail Caterpillar (Papilio palamedes).

Most damages to this species are noted in Florida but they can also apply to other related species found in North Carolina.

The late instar caterpillar causes curled leaves on these hosts and may eventually kill the host in the absence of a true predator.

One of the reasons this caterpillar still manages to kill red bays is due to its camouflaging colors and habits.

The early growth caterpillar stage is when the species hides in curled leaves. Large eyespots on its head also keep many predators away.

41. Hackberry Emperor Caterpillar

Hackberry Emperor Caterpillar

Hackberry Emperor Caterpillars (Asterocampa celtis) start life as pearl-white eggs.

They grow into large green caterpillars with brown and black horns.

Sugarberry or hackberry trees are the most impacted host species of this caterpillar.

Damages can be extensive but many caterpillars perish as prey for different types of Ichneumonid wasps.

One of the methods used to determine the impact of Hackberry Emperor Caterpillars is by assessing warts on tree bark.

Complete defoliation is possible, but still a rare sight.

42. Long-tailed Skipper Caterpillar

Long-tailed Skipper Caterpillar

This caterpillar species (Urbanus proteus) are among the few green species of North Carolina with additional yellow coloring and orange coloring.

Its green body has a base green color with a dark green dorsal stripe, a brown head, and orange marks on the head and the anal plate.

The first broad appears up until June with the second brood coming later in September or October.

44. White-dotted Prominent Caterpillar

White-dotted Prominent Caterpillar

Oak trees are the main host of the White-dotted Prominent Caterpillars (Nadata gibbosa).

As with other species feeding on oak, secondary hosts are also palatable. These include plums and roses.

The species has a bright green color that almost appears white. Side white stripes and tiny red dots are seen across its body.

The White-dotted Prominent Caterpillar gets its name from the tiny white dots scattered on its body.

The period between April and October is the time when this species is most active.

45. Silvery Checkerspot Caterpillar

Silvery Checkerspot Caterpillar

White dots are also seen in high numbers on the Silvery Checkerspot Caterpillar (Chlosyne nycteis).

This species is brown and black. It has black spines and tiny contrasting white dots on its body.

Its numerous status across many dry habitats are of low economic importance.

This species only feeds on asters. Different types of asters are preferred by the species starting with yellow ironweed.

46. Viceroy Caterpillar

Viceroy Caterpillar

Viceroy Caterpillars (Limenitis archippus) are mostly found next to the water in areas with willows.

Feeding on willow leaves, Viceroy Caterpillars have few natural predators due to their camouflaging colors.

The species mimic bird droppings with red, pink, black, and white colors.

Adults of the species are just atypical as caterpillars. Viceroy Butterflies are commonly seen feeding on feces.

Viceroy butterflies are also unpalatable to predators through the toxins consumed by their caterpillars.

Up to 3 Viceroy Caterpillar broods per year are seen in North Carolina. The eggs of the species may be confused with galls.

47. Common Eupithecia Moth Caterpillar

Green main color with large brown dorsal spots is specific to The Common Eupithecia Moth Caterpillar (Eupithecia miserulata).

This is a species that can have a detrimental effect on wildflowers and some trees.

It feeds on asters, cherries, and willow tree leaves.

The main defense of the species is to camouflage itself on leaves. This is why the brown spots on its body are variable, depending on the color of its host.

You can sometimes find this caterpillar on willows across the state, up to November.

48. Yellow-striped Oakworm

Anisota peigleri
Yellow-striped Oakworm. Image by Vijay Barve via inaturalist

Various types of oak such as Southern red oak are the hosts of the Yellow-striped Oakworm (Anisota peigleri).

This is a black caterpillar showing contrasting yellow dorsal stripes.

Its impact on local oak trees is still minor, but there’s always a risk of an outbreak and defoliation as in Florida.

The species needs to be managed early. Removing the eggs of the species from the leaves is a common management technique.

Its eggs are yellow and found both on the upper and the lower side of the leaves.

Maintaining proper tree health, pruning, and watering are good preventive measures against the species.

Unhealthy laurel oaks tend to be the most exposed species to Yellow-striped Oakworm defoliation.
