The term 'Stage After Pupation' refers to the final stage of an insect's life cycle, known as the Imago stage. This is when the insect has reached its adult form and is ready to reproduce. The Imago stage is also known as the imaginal stage or the perfect stage. During this stage, the insect will have fully developed wings and other features that are necessary for it to survive in its environment. The Imago stage is the last stage before the insect dies.
