Fruit fly biology


Fruit fly -Drosophila melanogaster

Fruit fly, “Drosophila melanogaster”

Drosophilidae (fruit flies) are a large family of small flies attracted to and breeding in fermented material.
They are typically an outdoor species feeding on sap from plants and rotting fruit. They may become a nuisance indoors when vegetable matter is fermenting.
In addition certain Drosophilia species are attracted to specific products such as vinegar, beer, fruit or sour milk.
Fruit flies lay about 800 eggs in total in batches of 20 eggs a day. Larvae have 3 skin molts and migrate towards the dry part of the medium before pupating. The metamorphosis from egg to adult can be as short as 7 days under favourable conditions.
