Contrasting color caterpillars are often yellow and black. Many caterpillars are green but those that are yellow and black can sometimes prove poisonous to predators.
Poison glands are rare on yellow and black caterpillars as they primarily rely on vivid coloring to keep predators away.
Some caterpillars come in additional colors, primarily brown, red, and white.
Alternating colors are specific to others during various growth stages.
Some caterpillars are only yellow and black in a certain growth period before pupation.
Most yellow and black caterpillars in North America are seen in one or multiple, sometimes overlapping, broods each year.
They have specific host plants they feed on and they appear in specific periods.
1. Police Car Moth Caterpillar
Police Car Moth Caterpillars (Gnophaela vermiculata) are dominated by black and yellow colors.
A base black color is contrasted by larger yellow patches across the lateral sides and a brown head.
These remain the colors of the caterpillar up to its final growth stages when it finally takes on black and white colors which are further seen on the emerging moth.
Host plant preferences influence the coloring of the species as it’s often seen on yellow flowers as a caterpillar and even as an adult moth.
Gromwells and stickseeds are among the common host plants of the caterpillar.
Adult moths are seen on some of the most common yellow flowers in open areas, goldenrods.
2. Dagger Caterpillar
Smeared Dagger Caterpillars (Acronicta oblinita) are sometimes known to sting. Sharp spikes across the body make the species less appealing to its predators.
Yellow and black colors are specific to the Smeared Dagger Caterpillar at various growth stages.
This is a species that has alternating longitudinal black and yellow bands across its body. Red bands appear in the later growth stages across its body as well.
The pupal stage of the species is marked by dark brown coloring.
Smeared Dagger caterpillars feed on grasses, tree leaves, and various shrubs.
These caterpillars are a minor pest of corn and clover.
3. Red-humped Caterpillar
Red-humped Caterpillars (Oedemasia concinna) are a known type of pest across Southern US states. It’s a major crop pest in some areas of California.
It begins life as a small spherical yellow egg laid in clumps, on the underside of leaves.
It then grows to a black and yellow caterpillar with either a red or a brown head.
This species feeds on the leaves of walnut, plum, pear, willow, and other trees.
It impacts crops in their early stages the most, as this is when the Red-humped Caterpillar feeds and lives in groups.
Pesticides are routinely used against this species. Biological control measures are mostly based on parasitic wasp management.
4. Yellow-necked Caterpillar
This species of caterpillar (Datana ministra) becomes black and yellow as it grows.
It appears brown and yellow as it emerges to become black with yellow stripes and brown spots in its later growth stages.
This species prefers willow and oak tree leaves which it consumes almost entirely.
Overwintering in a pupal stage is specific to the species. The pupa forms in the ground, under host oak and willow trees.
The pupa remains in the ground until the first weeks of spring.
Yellow-necked Caterpillars are generally found in Eastern North America with a growing presence on the Pacific Coast as well.
5. Brown-hooded Owlet Caterpillar
A combination of yellow and black contrasting colors makes the Brown-hooded Owlet Caterpillar (Cucullia convexipennis) unique.
This species has yellow bands and stripes. The bands have white tips.
Multiple black stripes and bands are also seen across its body in its first growth stages to have 2 additional brown bands in its later growth stages.
The ventral side of its body is marked by contrasting black and yellow stripes as well.
Much of the natural habitat of the species impacts its coloring.
Brown-hooded Owlet Caterpillars are mostly seen on goldenrod. Its preferred habitat covers dry areas of the Northeastern United States.
6. Cinnabar Moth Caterpillar
Yellow and black coloring dominates the appearance of Cinnabar Moth Caterpillars (Tyria jacobaeae) through their growth stages.
Alternating black and yellow bands cover the body of the species.
Adult moths have black and red colors.
The caterpillars of the Cinnabar Moth are known to be cannibalistic. They eat other larvae of the same species found on the same plant, typically ragwort.
A high level of defoliation and high appetite makes this species consume its host plant completely before pupation.
As a result, the caterpillar turns cannibalistic with no other available food.
These caterpillars also have natural predators such as various types of red ants.
7. Monarch Caterpillar
Monarch butterflies (Danaus plexippus) are some of the most common species in North America. Their caterpillar represents one of the yellow and black species that’s easy to spot as a result.
Alternating black, yellow, and white bands make up the bulk of the coloring this species is known for.
Thin yellow, white, and black bands cover its body.
Monarch Caterpillars are a known species of milkweeds, which may be poisonous to other species.
These caterpillars absorb the poisons in the plant which give it a foul taste to its predators.
While known to use milkweeds as a host species, Monarch caterpillars can also eat thistles, goldenrod, and a wide range of asters.
Monarch Caterpillars are among the few species with green pupa with yellow bands.
8. White-marked Tussock Moth Caterpillar
Black and yellow colors are also specific to the White-marked Tussock Moth Caterpillar (Orgyia leucostigma).
