Answer:
The pupa is comma-shaped when viewed from the side. This is a transitional stage between larva and adult. The pupae does not feed, but undergoes radical metamorphosis. The head and thorax are merged into a cephalothorax with the abdomen curving around underneath.
Explanation:
The pupa of many moths is protected inside a coccoon of silk. This stage can last from a few weeks, a month or even longer. Some species have a pupal stage that lasts for two years. It may look like nothing is going on but big changes are happening inside. Special cells that were present in the larva are now growing rapidly.
