Cocoon:

When about to pupate, the larva constructs a cocoon of fibers from palm. The cocoon is oval in shape, with an average length of 60 mm and a width of 30 mm.

Pupa:

The pupa is at first cream colored but later turns brown. The head is bent ventrally, the rostrum reaching the tibiae of the first pair of legs. The antennae and eyes are quite prominent. The elytra and wings are brought down ventrally, passing underneath the femora and tibiae of the second pair of legs, overlapping the third pair of legs and meeting in the middle of the abdomen.

The average length of  the pupa is 35 mm and the width is 15 mm.
