Morphology of the Tephritidae

The fruit or bored flies (Tephritidae, earlier also Trypetidae) are a family of flies (Brachycera). Worldwide there are around 4700 species in almost 500 genera. About 264 species in 68 genera live in Europe . In the Nearctic there are more than 360 species in 62 genera. The Tephritidae should not be confused with the fruit flies (Drosophilidae), which are also referred to as “fruit flies” in German.


They are small to medium-sized flies with conspicuously drawn wings. In addition to the compound eyes , the animals also have point eyes ( Ocelli ). Their antennae are three-segmented, their mouthparts are well developed. The females have a fold-out laying tube ( ovipositor ).

Way of life

The adults usually only have a very short lifespan of several days.

The maggot-shaped larvae of the animals live phytophagus almost exclusively inside plants and are found in almost all parts of the plants. Some species also form plant galls . There are also types such as B. Euphranta toxoneura , which live parasitically in the galls of other insects. The females pierce their eggs directly into the plants and fruits with a laying tube. Drill flies of the genus Bactrocera can cause crop failures of up to 100% in olive plantations .

There are numerous species that can cause significant damage in agriculture and fruit growing . In cherry plantations z. B. the trees with nets are protected against the cherry fruit fly ( Rhagoletis cerasi ), whose larvae develop in the cherries.
