What are yellow caterpillars?
Yellow caterpillars are the larvae of butterflies and moths. They go through a metamorphosis to develop into adult insects. When caterpillars first hatch from their eggs, they are black, white, or green. As they grow, they may change color several times before becoming adults. Yellow caterpillars turn into beautiful moths or butterflies. Some are fuzzy, and others have the body type of a typical caterpillar. Sometimes, some species of yellow fuzzy caterpillars can be poisonous.
Caterpillars generally eat plants, but some species feed on other insects and dead animals. They have six legs in the front and a few pairs of prolegs along the rest of their bodies that allow them to move around.
Caterpillars spend much of their time eating until they grow enough to make a cocoon or chrysalis. In this form, they rest while their bodies change through metamorphosis into adult insects with wings.

The caterpillar of the yellow poplar (Lepidoptera: Geometridae) is a common sight in eastern North America. Most caterpillars have a row of spiky ‘ears,’ running from head to hind end, and six rows of ‘feet’ on either side with soft long white bristles. These caterpillars are well camouflaged and can be found among leaves and twigs of deciduous trees.
In some species, the ‘ears’ are not located at the top of the caterpillar’s head but instead run along each side. This species has bodies that are covered in stiff hairs: setae (singular seta). The setae may be quite long and pointed or short and blunt; in some species, both kinds are present. In other species, the body is soft and furry without setae.
