Life through the lens
Introduction: Drosophila
The common fruit fly, Drosophila melanogaster, has been used as a model organism in research for nearly a century. Today, Drosophila are used to study topics from basic developmental biology (how complex organisms form) to the genetics and biochemistry of behavior.

Drosophila melanogaster pupae development
Drosophila pupae that have been removed from their pupae case complete their last few days of development into mature fruit flies.

Elapsed time about 5 days.
Pupae were dissected from their pupae cases and placed between a slide and coverslip with silicon spacers. The movie was taken on a dissecting microscope with a 2.5x objective and digital camera.
