The next stage is for the caterpillar (which is known as a pupa in this stage) to enter a chrysalis for about ten days. (The chrysalis is not a cocoon; a cocoon is a protective casing made out of [[silk]] by certain types of larvae, such as the caterpillars of typical [[moth]]s.) The chrysalis will become transparent about 24 hours before the pupa escapes and becomes a butterfly. <ref>http://adver-net.com/Monemerg.html</ref> The butterfly will struggle to escape the chrysalis, but this process gives it strength. Within several hours, the butterfly will have the ability to fly. | The next stage is for the caterpillar (which is known as a pupa in this stage) to enter a chrysalis for about ten days.
