I was digging in my backyard butterfly garden, when I came upon an earthen chamber. I found a cocoon, inside this earthen chamber. I took this cocoon with me, back to my house. Inside my house, I opened up this cocoon, so I could see its pupa. This pupa, was dark brown in color. This pupa, was one and one half inches long, and one half of an inch wide. On one end of this pupa, there were two, backward pointing spines. These spines, were three eights of an inch long. Some time later, this pupa eclosed into a beautiful Imperial Moth. Order: Lepidoptera Family: Saturniidae Genus: Eacles Species: imperialis When the caterpillars are ready to pupate, they burrow underground. When they are ready to pupate, they wrap themselves in silken cocoons, and surround themselves in earthen chambers, using plant material to blend in. Pupae are dark brown, with backward pointing spines, on the posterior end. This moth, spends the winter as a pupa in the soil. Adults emerge in the spring. Adults are nocturnal, and come to lights.
Deciduous, mixed, and coniferous forests. Deciduous and evergreen forests.
