What is the Difference Between Male and Female Fruit Flies?
🆚 Go to Comparative Table 🆚The main differences between male and female fruit flies (Drosophila melanogaster) can be found in their size, color, and abdomen shape. Here are the key distinctions:
- Size: Female fruit flies are generally larger than males, with longer abdomens. When comparing two flies, the smaller one is typically male.
- Color: The abdomen of male fruit flies has darker and thicker stripes compared to females, which have lighter and finer stripes.
- Abdomen Shape: The male fruit fly's abdomen is rounded at the bottom, while the female's is pointed.
- Sex Combs: Sex combs are located on the forelegs of male flies and look like thick black lines right before the joint. They are raised a little bit off the leg and pointed at the end.
By observing these differences, it is possible to distinguish between male and female fruit flies.

Comparative Table: Male vs Female Fruit Flies
Here is a table comparing the differences between male and female fruit flies (Drosophila melanogaster):
Characteristic | Male | Female |
---|---|---|
Abdomen Length | Short abdomen with few stripes | Longer abdomen with more stripes |
Abdomen Color | Darker and more rounded abdomen | Lighter and pointed abdomen |
Stripes | Stripes meld together and become dark toward the back | Stripes are finer |
Sex Combs | Present on the first pair of legs | Not present |
Fruit flies are sexually dimorphic, meaning males and females have noticeable differences. Males generally have a shorter, darker, and more rounded abdomen, while females have a longer, lighter, and pointed abdomen with more stripes. Males also have tarsal sex combs on their first pair of legs, which are black and distinctive.
