How to identify male and female fruit flies

Male and female identification of fruit flies can be carried out by observing external morphology and behavior. The following is a detailed introduction to the identification of male and female fruit flies:

External form identification:

Body size:

Male fruit flies are generally slightly smaller than females, but this difference may be less noticeable because fruit flies are generally smaller in size.

Abdominal shape:

At the end of the abdomen, male fruit flies have a pair of conspicuous penises and genitals; females have no similar organs in this area.

Abdomen color:

Female fruit flies usually have a fatter belly and may have a few pale to yellow eggs.

Male fruit flies generally have a slimmer and more uniformly colored abdomen.

Behavior identification:

Mating behavior:

During the breeding season, the mating behavior of fruit flies can be observed to identify the sex. Female fruit flies are often found actively releasing chemicals to attract male fruit flies. If fruit flies are observed mating, the male will tend to be above and the female below.

Differences in food habits:

In laboratory cultures, female fruit flies were found to generally prefer sugar water or yeast, while males preferred alcohol.

After mastering the external morphological and behavioral characteristics, you can use these methods to identify the sex of fruit flies relatively accurately. This is critical for anyone who wants to conduct fruit fly research or other related experiments.
