Imaginal Disks

 

histoblasts, clusters of undifferentiated cells in the bodies of the larvae of insects, nemerteans, and echinoderms, from which the final (definitive) organs are formed during the metamorphosis of the larva to the adult animal. Specifically, imaginal disks are characteristic of all insects with complete metamorphosis and of some with complex incomplete metamorphosis (Aleyrodidae, Coccidae).
