Hydei and repleta have such thoraxes, but maybe more species. I have no experience with them. |

Yes, a species of repleta-group, but not the proper D. repleta. Difficult to tell more on the base of this picture. |

Why would this not be D. repleta? The size of the lateral light patches looks good, and there is a slight darkening visible at the costal break. D. hydei can be excluded, and D. mercatorium should not have such large abdominal lateral patches Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated. My Diptera observations (and other living forms) can be found here, and corrections or comments over there would also be appreciated. |

Maybe I am wrong, but the darkening at the costal break is barely visible, it may be an artifact of the photo - a similar "darkening" can be seen at the basalmost break of costa. Concerning the lateral pale patches on abdomen, they look more like in D. mercatorum (larger than in D. repleta, not vice versa). Moreover, procoxa does not seem to be dark, contrary to D. repleta. If I should have to give an opinion, D. mercatorum seems me relatively most probable candidate, but it seems me too courrageous statement - on the base of only this picture. |

Ha! That was my wrong memory - I was certain that repleta was the one with the larger patches. Now I am in line with Jan. Somewhere I read that the abdominal distal stripes in mercatorum are thinner than in repleta Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

Here are 2 other photos taken today at the same place for more details. Do you have a better idea of the species is this Drosophila ?

It should be mercatorum or hydei. Male of D. hydei has a row of longer setae on protarsi, but these are not well discernible in pictures. Specimens should be kept; D. mercatorum has not been published from France as yet, though its occurence there is probable. |

Even on the last 2 photos is it not visible enough for identification? so here is another photo where the row of setae is better visible with the light background.

Even the last photo does not seem to me quite deciding. Keep the flies if possible, I may inspect them. |
