What does Della, the wasp artist, symbolize in the novel, Akakta Witch?

Della, the wasp artist that hatches from the Junk Man’s egg towards the end of the novel, represents Sunny’s progress as a Leopard Person. When the wasp is first born, it designs a castle out of crumbs. This aligns with Sunny’s beginning as she only had her home to comfort her. Later, after the defeat of the Black Hat, the wasp builds a replica of him, only to ensure that his head gets blown off by the end. This marks the end of Sunny’s current journey, and the removal of such a big threat from her life.
