Zaprionus tuberculatus

Zaprionus tuberculatus (commonly known as the vinegar fly or the pomace fly) is a member of the subgenus and genus Zaprionus, family Drosophilidae, and order Diptera. It is an invasive fruit fly that originated in Africa, but can also be found in Europe and Asia. The fly earned its common name, the "vinegar fly", because researchers frequently captured the species using vinegar traps. Z. tuberculatus was previously considered a strictly tropical fly, but evidence of invasion to nontropical regions such as Turkey has been shown. This fly typically resides on rotting fruit, and the larvae have been found to develop on 49 species of fruits. The life cycle of the fly depends on the temperature of the environment as males are sterile at or above 30 degrees Celsius. It is reddish-brick colored and contains four longitudinal stripes down its head and body. The courtship behavior includes song singing and complex dance rituals. In regard to other organisms, Z. tuberculatus is considered a secondary pest to fruit and a potential threat to ecosystems it invades. A close relative, Z. indianus is an invasive fly species that infests fig orchards.
