Drosophila melanogaster! I think. I think that's a sex comb I can see on the foreleg folded underneath, and its certainly not D. simulans. If this was taken in Africa, or if that is not a sex comb, it becomes harder... Do you have any more images? |

Ottawa Canada MND Drosophilidae gives 1,4,9,10,17,18,19,20 to Drosophila OK. What details needed to confirm D.melanogaster? John Sankey attached the following image:  [49.37Kb] Edited by John Sankey on 16-10-2012 01:09 |

As someone will no doubt point out to me soon..... I was so obsessed with that black blob being a sex comb that I failed (embarrassingly!) to spot that this fly is in fact female. This is acutely embarrassing. I still stand by Dmel as a good guess, though Dsim can't easily be ruled out. (Black band on penultimate tergite reaches the sternite suggests Dmel). Other northern european yellowish drosophila can be ruled out by looking at the black bands on the tergites: if there's a gap in the middle of its back it is subgenus Drosophila (and thus not melanogaster) |

And also I've just noticed that that you're in Ottawa. I shall give up. (The guess still stands, but I I don't know the North American Drosophila.) |
