What stage comes between larva and adult in the life cycle of an insect?

In the life cycle of an insect that undergoes complete metamorphosis, the stage that comes between larva and adult is the pupa stage. During this phase, the larva transforms into its adult form. The pupa acts as a transitional state where the organism undergoes significant internal changes as it develops new structures necessary for its adult form, such as wings and reproductive organs.

The larva stage is an earlier part of the lifecycle where the insect primarily focuses on feeding and growth in preparation for the transformation. The egg stage is the very beginning of the life cycle, where the insect first develops, while the adult stage follows after the pupa. The pupa is crucial as it signifies the period of transformation, leading to the emergence of the fully formed adult insect. This process is critical for the development of many insect species, allowing them to undergo drastic changes from one life stage to another.
