A single fertile female can lay hundreds of eggs and drosophila embryogenesis lasts approximately 24 h. Egg, larva, pupa, and adult.

At 25°c it takes drosophila only 10 days to go from egg to adult. Drosophila is a holometabolous insect —that is, an insect that has a larval and a pupal stage prior to the adult stage. The life cycle consists of four distinct stages: Their life cycle is broken down into 4 stages: Thus, goes on the cycle of life. When kept at room temperature (77° f), a drosophila egg requires 8.5 days to develop into an adult; Figure 3a shows that adult males typically live markedly shorter as temperature is increased. How many hours does it take for a drosophila melanogaster egg to become an adult fly? (hemimetabolous insects, on the other hand, have nymph stages preceding the adult.) the adu...
