As the caterpillars grow larger into the second larval instar, they become yellow green. During the third, fourth, and fifth instars, the cecropia moth becomes rather large and bluish green. At these final stages, the tubercles become blue, yellow or orange, depending on location on the body, while the black hairs are eventually lost. The caterpillars reach maturity in autumn and are about 4 to 4.5 inches (100 to 110 mm) long.

The parasitoid releases chemicals that override the regulatory mechanisms of the caterpillar. Once the parasitoid has grown enough, it induces the caterpillar to pupate. Once the caterpillars pupate, the parasitoid larvae themselves pupate, killing the cecropia pupa.

The body is hairy, with reddish coloring on the anterior, and fading to reddish/whitish. The abdomen has alternating bands of red and white.

Upon reaching adulthood, their size is variable. They are usually quite large, with a wingspan of about 5 to 7 inches (130 to 180 mm). The cecropia moth's wings are brownish with red near the base of the forewing. There are crescent-shaped spots of red with whitish centers on all wings, but are

After mating, the female will lay up to one hundred eggs. These eggs are a mottled reddish brown and are usually found on either side of a host leaf. These eggs will eventually hatch into tiny black caterpillars.

Once the caterpillars reach maturity, they spin large brown cocoons longways on trees or wooden structures. They will then emerge as adults in the first two weeks of seasonally warm weather in early summer.
