This species parasitizes in the larvae of flies of the genus Drosophila and Fabomyia. It has been recorded as a parasitoid of the following species so far: Drosophila ambigua, Drosophila auraria, Drosophila busckii, Drosophila funebris, Drosophila kuntzei, Drosophila melanogaster, Drosophila neozelandica, Drosophila obscura, Drosophila simularis, Drosophila subobscura, Drosophila suzukii and Fabomyia medicaginis. Most of these species also occur in Germany and thus can serve as host species in Germany. Interestingly, the fact that it parasitizes the fruit crop pest species Drosophila suzukii is making Asobara tabida a potential biological control agent; however, there is evidence that Drosophila suzukii is not a prime host and is only rarely used to deposit eggs (Chabert et al. 2012).

The flight period and the number of generations is incompletely known. Peris-Felipo (2016) lists a specimen that has been collected in August suggesting that the adults fly in the late summer.
