Hi, Fly addicts Unless I am greatly mistaken (it would not be the first, nor the last time  ) this is Napomyza gymnostoma, agromizidae. It was reared from a pupa collected from leak stems in my garden (Heron, Belgium) and hatched today March 13 2008.It appears to be becoming a rather too common pest of alliaceae, but there aren't too many pictures on the www.

I had these in large numbers a week or so ago. Hopefully someone can confirm the id.

Thanks for your comments. I do not have access to that description, so I cannot really comment. However, what else could it be, considering where it comes from, and its habitus? Philippe |

I think my flies emerged from the humus-rich soil meant for flowers.

The pupa from which mine emerged where collected from the leak stems themselves. They were embedded in the outer leaves, at the end of a "mine'. They looked just like the few pictures of Napomyza pupae on the www. That's why I think they are likely to be N. gymnostoma. Now I also found pictures/drawings of adult Napomyza cichorii, and they were extremely similar (except perhaps for the yellow knees). But then the host plant is different of course. Philippe |
