Thus at 25o c the life cycle may be completed in about 10 days but at 20oC about 15 days are required. Drosophila cultures ought to be kept in room temperature where the temperature does not. As bridges between genetics and developmental biology are both built and traveled upon it becomes imperative that developmental biologists study Drosophila to aid in the.

The life cycle consists of four distinct stages. The length of the life cycle and of each stage is directly related to the temperature with warmer temperatures tending to increase the rate of development. Drosophila is a model organism particularly used in developmental biology because it is a holometabolous insect with major morphological differences occurring between larvae and adult animal metamorphosis 1The drosophila life.

Egg and pupa stages are sessile larvae move within the substrate and adults are highly vagile as their ability to fly enables their dispersal. These details are somewhat boring and are neither necessary nor sufficient to make a model organism great.
