Living With Imaginal Discs

Drosophila Pupae

The transformation from larvae to adults is rapid in flies such as Drosophila.  This makes them convenient to observe and record videos. As the Drosophila puparium is forming, cells of the imaginal discs that lay waiting inside the larva for a hormone signal, begin to rapidly divide and differentiate. As soon as the puparium is completed, the legs and wings of the adult appear under the cuticle. The Drosophila pupa forms inside the protective puparium. It is possible to remove the pupa from its puparium shortly after its formation and observe the pupa develop. A video of the process can be found here:
