"Imaginal discs" refers to specialized cells that exist in insects like butterflies and moths. These discs are responsible for the growth and transformation of an insect from its larval stage (caterpillar) to its adult stage (butterfly or moth). They contain all the information needed to create the adult insect's wings, legs, eyes, and other body parts. Essentially,
imaginal discs are like blueprints that guide the development of an insect's body during its metamorphosis.
