Some of the most common caterpillars that stand out are yellow. They represent the life stage of moths or butterflies and can be found in various regions of the world, including North America.
Seen in one or multiple broods per year, these caterpillars might appear poisonous and they tend to have fewer numbers of natural predators compared to other species.
Yellow caterpillars might be yellow through all of their life stages or they might turn yellow either in the first or in the last instars.
Caterpillars often have black or red contrasting colors as purely-yellow species are rare.
Are Yellow Caterpillars Poisonous?
The poisonous or toxic nature of yellow caterpillars is up for debate.
Even species that may cause skin reactions don’t cause these reactions in all humans.
Yellow Tussock moth caterpillars are among the most common species to cause welts.
This is a type of skin urticaria. Rashes of this type don’t require medical attention but they might be more intense in children on seniors.
It’s the hairs of these caterpillars that might cause skin rashes in case of direct contact.
Even hairs that have fallen off the caterpillar can cause similar reactions.
Most types of yellow caterpillars aren’t poisonous or dangerous to host plants or trees.
These types of caterpillars might become a problem when multiplying rapidly in high numbers. This might be the case in late summer for some species.
Insecticides might be used to control their numbers.
Refraining from direct contact, even when wearing gloves, is recommended when it comes to keeping welts away.
The following species of yellow caterpillars are found across North America. Some of them can cause mild skin irritation.
Most are only potential pests to their host plants or trees through defoliation. Some of these species also show yellow coloring in their final adult life cycle.
Types of Yellow Caterpillars
1. Spotted Apatelodes Moth Caterpillar
This type of caterpillar (Apatelodes torrefacta) has a vivid yellow color with a few tiny brown spots and stripes on its dorsal side.
Long yellow hairs cover the fuzzy caterpillar.
Black or dark brown contrasting spots are also seen on the species.
This caterpillar lives on Eastern North America’s common trees. It lives and feeds on oak leaves, maple, ash, cherry, and plum trees.
The adult Spotted Apatelodes Moth Caterpillar doesn’t carry on its yellow color into adulthood.
Once they reach the adult stage, moths of this family are gray, dark brown, and black. They blend in with the environment without any vivid colors.
The species grows up to a size of 42mm.
2. Cloudless Sulphur Caterpillar
Cloudless Sulphurs (Phoebis sennae) are marked by yellow colors across all life stages.
The caterpillar of this yellow butterfly is yellow itself. It has a uniform bright yellow color later showing light green bands across the body.
The species also has light yellow ventral coloring, making it an almost completely yellow caterpillar.
Cloudless Sulphur Caterpillars aren’t always as yellow. The emerging caterpillar in its early growth stages has a slight green tint.
Its yellow color richens as the species grows.
These types of caterpillars may be found on host plants with yellow flowers, which may explain their coloring.
Partridge peas are among the most common hosts of the caterpillar.
Its final size depends on its feeding habits and food availability as the caterpillar doesn’t feed on pollen as adults.
These caterpillars may reach a size of 45mm.
3. Spicebush Swallowtail Caterpillar
Spicebush Swallowtail Caterpillars (Papilio troilus) turn yellow in their later growth stages.
This caterpillar begins life as a brown species and it only turns yellow in its later instars.
The species seen in multiple broods in different areas of North America may also show brown or yellow color differentiation depending on the season.
The brown or yellow color of its pupa is also seen according to the seasons. A brown pupa is characteristic of Spicebush Swallowtail pupa in the winter while a yellow color may be seen in the summer.
Apart from the main yellow color (sometimes with green undertones), this caterpillar is also known for its large eyespots on the head.
Looking similar to a small snake, this caterpillar uses contrasting colors and eyespots to send off warning signs to predators.
4. Virginia Ctenucha Caterpillar
Virginia Ctenucha Caterpillars (Ctenucha virginica) have a mostly yellow color with significant white and black sections as well.
A hairy body is specific to the species in its early growth stages. Long yellow and black hairs decorate its body.
