On 16th October 2018 we trapped flies at the Font Groga site (Tibidabo mountain), on the city limits of Barcelona . The vegetation is typically Mediterranean, dominated by pines (Pinus pinea) and ilexes (Quercus ilex). As expected, the most abundant species was D. subobscura, because it presents a peak of expansion in autumn . D.simulans was at a fairly high frequency, due to its autumnal expansion period in Mediterranean populations. The invasive species D. suzukii was also found, and it seems that it has established a rather stable way in this place
