Black and Yellow Caterpillars (With Pictures) – Identification Guide

Caterpillars that feed on butterflies and moths are black and yellow caterpillars. Hairy bodies are seen on certain caterpillars, which may be black or yellow. Crawlers of all sizes may be found. Depending on the moth or butterfly species, the caterpillar may be black with yellow stripes or patterns.

Yellow caterpillars with fuzzy bodies and black spines or horns, for example, might be found. All black and yellow caterpillars eventually develop into magnificent flying butterflies, which they all share.

Caterpillars that become butterflies and moths don’t look anything like the black and yellow caterpillars. The magnificent orange and black monarch butterfly, for example, develops from the black and yellow striped monarch caterpillar. The lovely brown mottled tiger moth comes from the black and yellow fuzzy spotted tussock caterpillar.

This article will help you identify the various types of black and yellow caterpillars. Yellow and black caterpillars are also described and depicted in order for you to identify the moth or butterfly species that emerges following metamorphosis.

Are Black and Yellow Caterpillars Poisonous?

If you come into contact with most black and yellow caterpillars, they won’t sting you. The barbed spines of the yellow and black hairy spotted tussock caterpillar (Lophocampa maculata) can cause skin irritations, however. In addition, the monarch caterpillar (Danaus plexippus) and Cinnabar moth caterpillar (Tyria jacobaeae) produce poisons that may harm tiny birds or rodents.

Certain kinds of black and yellow caterpillars have the potential to be frightening. The horns, eye-like patterns, fuzzy bodies, and vivid yellow hues of these animals are used to repel potential predators at the head or tail end. Nonetheless, you shouldn’t be concerned about black and yellow caterpillars being poisonous. Nevertheless, any caterpillar with spines or tufts of tiny hairs should be avoided when handling it.

Black and Yellow Caterpillar Identification

Colors, distinguishing patterns, six legs, prolegs (stumpy-looking legs), hair or spines, and size can be used to identify black and yellow caterpillars. The plant the caterpillar is feeding on can also be used to identify some caterpillar species. For identification, you may also measure their length. It’s also important to remember that caterpillars go through multiple phases, or instars. As a result, an adult caterpillar and a caterpillar that has just emerged from the pupa may appear to be completely different.

Adult caterpillars’ last stages are examined in this article, which examines their distinguishing characteristics. The caterpillars that eat leaves are black and yellow, with worm-like habits and a Lepidoptera insect order. Caterpillars ranging from 2.5 cm to 5.5 cm (1 in to 14 cm) in length can be found striped and horned yellow and black.

Types of Black and Yellow Caterpillars (With Pictures) 

Let’s examine the various forms of yellow and black striped, fuzzy, hairy, and smooth caterpillars in further depth.

Monarch caterpillar (Danaus plexippus)

The monarch caterpillar is a striped black, yellow, and white caterpillar with black, white, and yellow stripes on its body. The yellow, white, and black bands of the caterpillar’s body, as well as its two black tentacles at each end, distinguish it from other species.

The monarch caterpillar, which is black and yellow in color, grows to be 1.7″ (4.5 cm) long. The monarch caterpillar is feeding on milkweed, which you may see. The diet of monarch butterflies makes them one of the few poisonous black and yellow butterflies.

Black and Yellow Caterpillar Identification

The black, yellow, and white stripes on monarch caterpillars are easily distinguished. Milkweed leaves are the source of food for monarch caterpillars.

White-Marked Tussock Furry Horned Caterpillar (Orgyia leucostigma)

The white-marked tussock is a yellow and black caterpillar that becomes a huge brown moth with a distinctive appearance. The red head and yellowish hairs on the yellow-and-black body distinguish the spiny caterpillar. Long black spines protrude from the body as well. This 1.3-inch (3.5 cm) caterpillar is unique and fuzzy. Due to its urticating hairs, the white-marked tussock larva is a stinging caterpillar that may cause allergic reactions in humans.

Black and Yellow Caterpillar Identification

The stinging hairs on the white-marked tussock caterpillar’s tufts are yellowish-white, and the caterpillar has a black body with yellow stripes.

Yellow Spotted Tussock Moth Caterpillar (Lophocampa maculata)

With its fuzzy yellow and black hairs, the yellow-spotted tussock caterpillar has a distinct appearance. The hairy black ends and large yellow band around the body’s center are two characteristics of this tufty caterpillar. Between the ends of the hairs, you’ll see thin tufts of white hair. The spines on the black and yellow caterpillars can sting you if you touch them, although they aren’t poisonous.

Black and Yellow Caterpillar Identification

The yellow-spotted tussock’s unique wide black and yellow fuzzy stripes and tufts of white hairs make it easy to spot. Oak, willow, maple, and alder leaves are all eaten by these caterpillars.

Six-Spot Burnet Caterpillar (Zygaena filipendulae)

The six-spot burnet caterpillar has tiny spikes and a fat yellow body with black markings. This yellow and black caterpillar is about 0.8″ (2 cm) in length and is native to the United Kingdom. Tufts of spiky hairs cover the pale yellow and black sections when you get up close.

During the day, this uncommon yellow and black caterpillar turns into a stunning black moth. The six red dots on the gorgeous butterfly’s glossy black wings inspired the term “six-spot” burnet.

Black and Yellow Caterpillar Identification

Look for horizontal lines of black patterns on a pale, almost translucent yellow body to help identify the six-spot burnet caterpillar.

Queen Caterpillar (Danaus gilippus)

The queen butterfly caterpillar has black stripes with yellow dots, white lines, and black tentacles. It is a big black caterpillar with yellow dots. This smooth caterpillar has a black head with white rings and is related to the monarch caterpillar. White stripes are common, but yellow, blue, green, or brown stripes may also be seen. This black, white, and yellow striped caterpillar transforms into a spectacular red butterfly after emerging from its pupal stage.

Black and Yellow Caterpillar Identification

The six black fleshy tentacles, black body with white transverse bands, and two large yellow dots on each segment help to identify the queen caterpillar.

Catalpa Sphinx (Ceratomia catalpae)

As it grows up, the catalpa caterpillar becomes a lustrous jet black with yellow borders down each side. Immature larvae are frequently pale in color with little patterns. Until they are completely black, they become darker. Their yellow markings down the sides are another distinguishing mark. On each side of the caterpillar, these join to create a yellow row.

The black and yellow caterpillar has black dots on its sides, and it is also known as the Catawba worm. The length of an adult Catalpa caterpillar can be up to 2 inches (5 cm). The head and tapering tail end are black. In states such as Texas, Florida, Maine, and Iowa, catalpa worms can be found eating native catalpa trees or cigar trees. Large brown catalpa sphinx moths emerge from worm-like yellow and black caterpillars.

Black and Yellow Caterpillar Identification

The black body with yellow and black markings along the sides of the catalpa caterpillar is a good way to identify it.

Giant Sphinx caterpillar (Pseudosphinx tetrio)

The crimson/orange head and tail of the yellow and black striped Giant Sphinx caterpillar The orange prolegs, crimson-orange head, and black horns at the orangey tail of this huge caterpillar are all obvious. Caterpillars of the giant sphinx can grow to be over 6 inches (15 cm). If tiny creatures or birds consume it, the big sphinx is a poisonous yellow and black caterpillar. It’s been known to bite when trapped and has barbed, stinging hairs.

Black and Yellow Caterpillar Identification

The enormous sphinx has an orange tail, head, and prolegs to help distinguish it from the giant sphinx, which has distinctive yellow bands on its jet-black body.

Black and Yellow Zebra caterpillar (Melanchra picta)

The reddish-brown head of the black and yellow striped zebra caterpillar distinguishes it from other caterpillars. There are also thinner black stripes around the segments, giving the caterpillar a zebra-like pattern, as an unusual type of caterpillar. The underside of the zebra caterpillar is also reddish-brown. The caterpillars have black and yellow stripes that are 1.4 to 1.6 inches (3.5 to 4 cm) long.

Black and Yellow Caterpillar Identification

Look for the wide cream-yellow stripes and thinner black stripes down the length of a medium-sized caterpillar to determine whether it’s a zebra caterpillar.

Common Sheep Moth Caterpillar (Hemileuca eglanterina)

The brownish-black body and tufts of black spiky and yellow or orange spines on the common sheep moth caterpillar make it look menacing. Bitter cherry, bitterbrush, wild roses, and mountain lilac leaves are all eaten by this unusual caterpillar. The caterpillar becomes a beautiful orange or pink moth as it matures. It has an unusual appearance of black and yellow.

Black and Yellow Caterpillar Identification

To help identify this black caterpillar, look for whorls of yellowish or orange tufts on the back.

Yellow and Black Cinnabar Caterpillar (Tyria jacobaeae)

The cinnabar caterpillar has fine hairs on its body and yellow and black stripes. Thin hair-like black or white spines do not grow abundantly on its body, as you can see. The poisonous caterpillar’s bright yellow and black colors serve as a deterrent to predators. The yellow and black striped cinnabar caterpillar is seen eating ragwort leaves. The caterpillar becomes a stunning black and red moth after transforming yellow and black.

Black and Yellow Caterpillar Identification

The cinnabar caterpillar can be identified by looking for a jet-black and yellow striped caterpillar that grows up to 1.2″ (3 cm) long.

Brown-Hooded Owlet (Cucullia convexipennis)

The colorful, brown-hooded owlet caterpillar has yellow stripes and red dots on its black body and is a lustrous black caterpillar. A horizontal red line runs lengthwise just over the glossy black legs, which you may also see. It has a bright black head with yellow patterns, and is also known as the calico paint caterpillar.

Black and Yellow Caterpillar Identification

The yellow and white stripes on the brown-hooded owlet caterpillar’s body form a wide horizontal stripe down the middle. The caterpillar is about 1 inch (2.5 cm) long and is black in color.

Black Swallowtail Caterpillar (Papilio polyxenes)

The black swallowtail caterpillar has a green body with black and yellow stripes and dots. It’s a mature caterpillar. The caterpillar’s segments are covered with black bands with yellow dots. The prolegs, which are white or green in color with black and yellow patterns, will also catch your attention. As these caterpillars grow up, they develop a butterfly larvae’s appearance. Caterpillars that are young feed on black and have a white band around the middle.

Black and Yellow Caterpillar Identification

The black bands and yellow dots on a bright green body are the identifying features of the black swallowtail caterpillar.

Yellownecked caterpillar (Datana ministra)

The yellownecked caterpillar is a black caterpillar with yellow stripes that run the length of the hairy body. The hairy caterpillar has white feathery spines, yellowish and black legs, and a black head, which you may also notice. If alarmed, the yellownecked caterpillar folds its body into a distinctive “U” shape.

Black and Yellow Caterpillar Identification

The longitudinal yellow stripes on a black hairy body, as well as the distinctive yellow and black feet, may be used to identify a yellownecked caterpillar.

Mullein Moth Caterpillar (Cucullia verbasci)

The mullein moth caterpillar is a striking long, fat caterpillar with yellow circles and black dots on a white or light green body that is distinguished by its white or light green body. This 2″ (5 cm) long caterpillar is easily recognized as it feeds on Buddeia plant leaves because of its brilliant colors. In July and August, mullein moth caterpillars may damage bushes if they are not controlled.

Black and Yellow Caterpillar Identification

Because of its black and yellow patterning on a white or pale grayish-green body, the yellow, black, and white Mullein moth caterpillar is unmistakable.

Grapeleaf Skeletonizer Caterpillar (Harrisina americana)

The grapeleaf skeletonizer has yellow bands and lines of black dots on its body, which helps to identify it. It also has small irritating hairs. Grapevine leaves have a underside that you can investigate for leaf-munching insects. When feeding, these caterpillars form a line and stand in a row. The grapeleaf skeletonizer is covered in itchy hairs, although it is not a poisonous yellow and black caterpillar.

Black and Yellow Caterpillar Identification

The bands of black dots on the black and yellow grapeleaf skeletonizer caterpillar differentiate it from others.

Redhumped Caterpillar (Schizura concinna)

The redhumped moth caterpillar has a brilliant yellow body with black and white horizontal stripes and lines on its head. The striped, yellow caterpillar’s red humps on the back are what give it its common name. Yellow and black redhumped caterpillars may be seen feeding in clusters on cottonwood, fruit trees, willow trees, and walnut trees.

Black and Yellow Caterpillar Identification

The crimsonhumped caterpillar has yellow and black stripes, short black fleshy tentacles, a crimson head, and crimson humps that distinguish it.

American Dagger Caterpillar (Acronicta americana)

The American dagger caterpillar has two sets of long, black hair-like spines on its back and one at its tail, which distinguishes it from other caterpillars. The glossy black head of the pale yellow hairy caterpillar is easily visible. Hickory, birch, maple, oak, and poplar trees are all home to the dagger moth caterpillar. The fuzzy yellow caterpillar becomes a magnificent brown moth after emerging from its pupa.

Black and Yellow Caterpillar Identification

Long, fine feathery hairs cover the body of the yellow American dagger moth caterpillar. After grasping it, it has a 2″ (5 cm) length and may cause skin irritation.

Smeared Dagger Moth Caterpillar (Acronicta oblinita)

The smeared dagger moth caterpillar has a black body with white markings on its back and a yellow wavy line down both sides. It has poisonous spine tufts all over it. This dagger moth caterpillar has jaggy-looking tufts of white or reddish-brown spines as a defense mechanism. If you handle the spiny caterpillar, it can also sting you. Fruit trees, shrubs, strawberry plants, willows, and oaks are common places for this pestiferous black and yellow caterpillar.

Black and Yellow Caterpillar Identification

The yellow longitudinal stripes along the bristly black body with white patterns on the back distinguishes the smeard dagger moth caterpillar.

Fall Webworm (Hyphantria cunea)

Fall webworms come in a variety of colors, from tiny yellow hairy caterpillars with black dots and long spikes to big orange hairy caterpillars. Some are pale yellow with black dots, while others are dark gray or green with light markings. A black dot and tufts of yellow or white bristles adorn each segment of these insects.

The tent-like structures built by yellowish hairy larvae are similar to those created by tent caterpillars. Walnut, cherry, crabapple, and other deciduous trees attract these yellow hairy caterpillars by chewing their way through leaves.

Black and Yellow Caterpillar Identification

Web nests hanging from the tips of hardwood tree branches in late summer and fall are easy to identify if you notice them. The yellow, hairy body of the fall webworms has black dots and long yellow spines, measuring 1.4″ (3.5 cm) long.

White Flannel Moth Caterpillar (Norape ovina)

The white flannel moth caterpillar features pairs of brilliant yellow spots on each segment and a yellow underside. Its poisonous spines may cause a severe sting. Tufts of long feathery spines on this stinging black and yellow caterpillar can cause skin irritation. As a result, keep your distance from it to avoid being bitten. Spectacular white hairy moths emerge from the yellow-dotted black caterpillars.

The black and yellow caterpillar has several black spines and two pairs of wavy antennae-like projections when viewed up close. The distinctive black and yellow striped caterpillar grows to be 1.18″ to 1.37″ (30–35 mm) in length when fully mature.

These caterpillars with black and yellow leaves are typically discovered biting through the leaves of deciduous trees. The juvenile larvae, which are black and white and look like bird droppings, are difficult to see. However, stripes with yellow and black bands and club-tipped spines develop as they grow.

The alder moth develops from the black and yellow striped caterpillar after pupation. With brown forewings and creamier mottled designs on the rear wings, it’s a kind of fuzzy moth.

Black and Yellow Caterpillar Identification

The glossy black cylindrical body of the peculiar black and yellow alder moth caterpillar has bright yellow stripes. The paddle-like spikes on the side of its segments are a distinguishing feature.

Amaryllis Borer Caterpillar (Brithys crini)

The amaryllis borer caterpillar has a reddish-brown head and yellow markings on its black body that distinguish it from other caterpillars. A little rounded rusty brown head and sparse fine setae cover the black and yellow caterpillar’s body. The 1.75″ (40 mm) long striped caterpillar reaches maturity.

This plant-damaging black and pale-yellow caterpillar eats on amaryllis and lily stems and leaves, also known as the lily borer, crinum borer, or Kew arches. Birds and other insects find the yellow-striped, black caterpillars unpalatable, making them poisonous to them. Boring into plant tissue, causing large holes, is how the caterpillars harm plants.

Black and Yellow Caterpillar Identification

The black body and faint-yellow bands that go around the segments of the amaryllis borer caterpillar distinguish it. The caterpillar’s body is cigar-shaped and has little bristle spikes, as seen in photographs.

Scarlet Tiger Moth Caterpillar (Callimorpha dominula)

The scarlet tiger moth larva is a spiky black caterpillar with yellow and white bands running lengthwise down its length. This black and yellow caterpillar has tufts of black spines around each segment. The cylindrical body of this caterpillar grows to 1.57″ to 1.77″ (40-45 mm) long and is cylindrical in shape.

This black caterpillar with yellow stripes feeds on a wide range of plants, including stinging nettle and common comfrey, due to its large size and spiky appearance. Before coming out the next spring, the caterpillars emerge in early spring and spend the winter in the ground.

The scarlet tiger moth caterpillar changes into a black and red moth with yellow, red, and white dots on its black forewings after the larval stage.

Black and Yellow Caterpillar Identification

The black cylindrical body, yellow stripes, white markings, and tufts of black spiny spines distinguish the scarlet tiger moth caterpillar from other caterpillars.

Lily Borer Caterpillar (Diaphone eumela)

The orange-headed striped black and light yellow lily borer caterpillar can be found on lily and amaryllis plants. A pale brown or orange head, red dots in each black band, and a yellowish patch at the rear end characterize the yellow and black “bug.” Caterpillars with yellow and black stripes grow up to 1.57 inches (40 mm). Pale yellow with black stripes, the lily borer caterpillars emerge.

The yellow caterpillar gets a speckled black and reddish orange look as it develops from bright caterpillars with orange markings. The amaryllis borer species is related to the Lily Borer Caterpillars. These black-striped, yellow caterpillars are frequently seen on lily and amaryllis plants, as the name indicates. The lily flower leaves and stems are left with tell-tale holes by the cigar-shaped larvae burrowing into plant tissue.

Black and Yellow Caterpillar Identification

The dark bands surrounding the yellow segments of the bright yellow and black lily borer caterpillar distinguish it.

Police Car Moth Caterpillar (Gnophaela vermiculata)

The larva of the police car moth is a spiky black caterpillar with brilliant yellow markings on its back, which is speckled with yellow dots. The spines of this species, like those of many other black caterpillars with spiky growth, develop in clusters around each segment.

A broken lateral band of color is formed by irregular yellow dots. The remarkable black caterpillar body is distinguished by iridescent blue dots on top of grayish-black spines and yellow markings. The yellow-spotted black caterpillar has an unusual appearance due to its rounded reddish-brown head. The color of immature larvae, on the other hand, is yellow rather than black.

The police car moth emerges as a stunning black and white moth from its silken cocoon, which is why it’s called that. The green lattice moth larva is another name for this caterpillar moth. The spiky black caterpillar is frequently seen eating nectar off of herbaceous flowers.

Black and Yellow Caterpillar Identification

A glossy-jet black body with yellow and metallic blue dots, as well as a reddish head, identify the police car moth.

Cabbage White Caterpillar (Pieris brassicae)

The yellow caterpillar has a black body with fine white hairs and is big to small in size. The caterpillar’s appearance changes as it goes through various stages of development. It is yellow and black in appearance. Before becoming grayish green and black before pupation, it turns from pale yellow to dark yellow.

The brown-headed hairy yellow caterpillars grow to be 1.57″ (40 mm) long. The yellowish-green, black-spotted caterpillar eats cabbage and other Brassica plants, as the name suggests. Brussels sprouts, swede, turnip, cauliflowers, and kohlrabi are among the crops that can be killed by big, overweight caterpillars.

The big cabbage white, sometimes known as cabbage butterfly or cabbage white, produces yellow and black caterpillars. The snow-white wings with brown tips distinguish this butterfly from others.

The yellow, black, and orange slug-like bug is sparsely covered in short, fine black hairs when seen up close. The length of a mature magpie moth caterpillar is 1.18″ (30 mm).

The looping movement of the yellow and black caterpillar as it crawls over plant leaves and stems is a distinguishing characteristic. Hawthorn, blackthorn, gooseberry, and Japanese spindle (Euonymus japonicus) leaves are commonly eaten by the black-speckled yellow caterpillar.

Black and Yellow Caterpillar Identification

Black spots cover the creamy-yellow body of the magpie moth caterpillar. In addition, a lateral orange band runs the length of its abdomen’s base.

White-Lined Sphinx Moth Caterpillar (Hyles lineata)

Depending on its growth phase, the larva of the white-lined sphinx moth may be yellow with black stripes running lengthwise. Little triangular black markings and brownish dots cover the sides of the enormous slug-like insect. The caterpillars reach 3.5 inches (88 mm) in length and are yellow with black markings.

Because of the various color variations, identifying the white-lined sphinx moth caterpillar might be difficult. The slender, cylindrical larvae may be dark green with black and white dots or lime green with a black or orange spike tail, depending on the climate. In North America, the yellow, black-striped caterpillars can be found growing in gardens and deserts. Fuchsia, tomato, apple, elm, evening primrose, and grapes are among the plant species they eat.

Black and Yellow Caterpillar Identification

The caterpillar of the white-lined sphinx moth has a worm-like body with black lateral stripes and brownish-black patterns down its back and sides. It is light green-yellowish in hue.

A rounded head with faint orange patterns distinguishes this unusual hairy black caterpillar. The caterpillar may be orange and black in color depending on the species. The grass eggar caterpillar reaches a length of 2.55 inches (65 mm) when it matures.

In late March and early April, hairy yellow and black caterpillars emerge from their eggs. Many types of blossoming grasses, shrubs, and deciduous trees are eaten by the hungry caterpillars. Peas, beans, and other Fabaceae species may support the adult fuzzy caterpillars. The black and yellow hairy caterpillar becomes an appealing fuzzy brown moth after pupating. In August and September, the russet-brown moths are active at night.

Black and Yellow Caterpillar Identification

A black-bodied, cylindrical caterpillar with yellowish-orange hairs, the grass eggar moth caterpillar is a larva. Several species, on the other hand, have an orange lateral stripe on their backs that gives them a grayish-white appearance.

Buff-Tip Moth Caterpillar (Phalera bucephala)

The larva from the buff-tip moth is a huge, cylindrical-shaped black caterpillar with fine hairs covering its hefty black body. It has yellow stripes and orange patches running lengthwise down each segment. Tufts of pale setae and a unique ‘V’ marking on a black globular head distinguish the easy-to-identify black and yellow striped caterpillar.

The buff-tip moth caterpillar grows to be 2″ to 3″ (50 – 75 mm) long with a slender tube-shaped body. It has a pattern that is described as trellised, and it has a covering of yellow, orange, and black. Several deciduous tree species, such as oak, beech, willow, and hazel, have an unusual caterpillar that is common.

It’s worth noting that the caterpillars have prickly spurs, yellow and black. When removing them from trees and bushes, you should use gloves.
