Life cycle of Drosophila Stages and duration. The rate of development is dependent on temperature being more rapid at higher temperatures. In holometabolous insects such as Drosophila the adult stage is morphologically different and much more mobile than all pre-adult life stages of the life cycle.

First instar one day in length Day 3. Some groups of cells complete this cycle in 75 minutes whereas other groups of cells take 175 minutes. Embryonic development which follows fertilization and the formation of the zygote occurs within the egg membrane.

Pupae stage lasts for 3 days and after pupation the adult fly hatched. Life Cycle of Drosophila melanogaster. The Drosophila Life Cycle.

The eggs hatch after half a day that is from 12 to 15 hours of laying which are about 05 mm in its size. Female lays eggs Day 1. From the stage of egg fertilisation up to adult life the life cycle of Drosophila lasts for close to 10 days at a temperature of about 25C.

The time length of the stages is approximate and is shown in hours for embryos and days for larvae and pupae. In the laboratory Drosophila melanogaster is usually cultured at 25 or 18C the latter mainly for maintaining stocks. Second instar one day in length Day 5.
