An imaginal disc is one of the parts of a holometabolous insect larva that will become a portion of the outside of the adult insect during the pupal transformation. The role of the imaginal disc in insect development was first elucidated by Jan Swammerdam. During the pupal stage, many larval structures are broken down, and adult structures, including the discs, undergo rapid development. Each disc everts and elongates, with the central portion of the disc becoming the distal part of whichever appendage it is forming: the wing, leg, antenna, etc. During the larval stage, the cells in the growing disc appear undifferentiated, but their developmental fate in the adult is already determined. The experiment that demonstrates this developmental commitment is to take an imaginal disc from a third instar larva, about to undergo pupation, and subdivide it and culture it in the body of a younger larva. Discs can be continuously cultured this way for many larval generations. When such a cultured disc is eventually implanted in the body of a larva that is allowed to pupate, the disc will develop into the structure it was originally determined to become. That is, an antenna disc can be cultured this way and will, almost always, become an antenna out of place, of course when final development is triggered by pupation. The study of imaginal discs in the fruit fly Drosophila melanogaster led to the discovery of homeotic mutations such as antennapedia , where the developmental fate of a disc could sometimes change.
Scientific: The imaginal cells are the parts of a caterpillar that hold the information of the butterfly. They are latent within the cell, until it is time for them to grow. Pupal and adult tissues form from imaginal cells. Clonal analysis and fate mapping of single, identified cells show that tracheal system remodeling at metamorphosis involves a classical imaginal cell population and a population of differentiated, functional larval tracheal cells that reenter the cell cycle and regain developmental potency. In late larvae, both populations are activated and proliferate, spread over and replace old branches, and diversify into various stalk and coiled tracheolar cells under control of fibroblast growth factor signaling. A much less boring explanation can be found in Scientific American! In this metaphor, our present society is the all-consuming caterpillar, and the world we envision is the soon-to-emerge beauty of the butterfly. My friend and collaborator Norie Huddle , in her book, Butterfly , is the originator of this meme, taking the idea from the world of biology to the world of societal dynamics. As we transform our society, do you think we will face opposition? It is time for us all to answer a higher imperative.
He envisioned a better future and encouraged us to step into it. Imagination is the basis for the creation of novelty; new ideas, new concepts, new everything. In biology, there is a term called Imaginal Cells. And they got that name for a reason. We all learned that caterpillars go through a metamorphosis and become butterflies. But few of us know the details of how this process actually takes place. How it happens is absolutely amazing. The end result, we know, is a butterfly. But the mindblowing thing here is that there is no structural similarity at all between a caterpillar and a butterfly. Inside of the chrysalis, the caterpillar actually dissolves into organic ooze.

This is what starts the process of creating a new form and structure. At first the Imaginal Cells — the seeds of future potential, which contain the blueprint of a flying creature — operate independently as single-cell organisms. But they persist, multiply, and form connections with each other.
The Imaginal Cells communicate more, creating larger and larger cooperative networks until they eventually hit a tipping point. And a butterfly is born. If you never knew about the process of metamorphosis, you would assume the caterpillar just consumes and consumes, until it exhausts its environment. Think about the general state of a caterpillar before it becomes a butterfly: mindless consumption.
Sounds familiar, right? Go to any city, any store or just turn on the TV, and the level of mindless consumption is hard to miss. Humanity has been that way for a while, but the paradigm is shifting. Then, when the new Imaginal Cells start popping up, they get attacked by the other cells. They get attacked and demonized by those who are still trapped in caterpillar mode.
Those who I just named were some of the first Imaginal Cells, the harbingers of a new level of consciousness. Now remember that more and more Imaginal Cells start to pop up. Then they begin to connect, work together and create the new being. It is a humanity that is so profoundly different than what we have seen, an emergent, higher-order collective.
Imaginal Cells: From Caterpillar To Butterfly After a period of ravenous consumption, the caterpillar finds a perch and forms a chrysalis. Our outdated version of humanity is the caterpillar, mindlessly consuming everything in sight.
