I found this insect on dead wood in our garden on the fringe of the Eifel hills (Germany) at the beginning of June. According to my ID books it should be a female of Tanyptera atrata, which seems to be ovipositing in the dead wood. I would be grateful for a confirmation or any other comments.

As nobody has responded yet, I'm going to add a second picture hoping enough details are visible.

Probably Pjotr didn't yet notice this post; in my opinion you are right. |

Thanks a lot for your comment, Carlo. I had a look at the photos again and found one more which might be helpful as it was taken from a different angle.

I shot a similar photo series in southern Brandenburg at the same time. My fly was even more colourful. With the key http://www.nev.nl...38-149.pdf I went straight to Tanyptera atrata. Though in your pictures the dimensions of the antennal segments and the colour of the trochanter are not clearly visible, the fully orange femora allow for the conclusion that yours is T. atrata, too.

Thank you, Sundew, for the good news and the first-class pictures. I'm also grateful to you for guiding me to the extremely useful internet key which is the sort of detailed key I had been looking for, but couldn't find. The wing pattern in the drawing also corresponds exactly with the one in the photos (particularly your second and my first picture). Carlo Monari, by the way, in his comment referred to Pjotr who is obviously one of the co-authors of your illustrated guide and also - I now realize - author of the excellent book The European Families of the Diptera which I recently bought. The diptera world, it seems, is a small world. Kind regards, Hans Theo K. Edited by HTK on 14-07-2013 20:25 |

Pjotr is also the author of the Catalogue of the Craneflies of the World (http://nlbif.eti....] where you can search the species. Unfortunately, his activities in the forum have become quite rare. You say, "The diptera world, it seems, is a small world." I would like to state more precisely that the Diptera world is giant, but the number of dipterists is so small! That's why we meet the same names again and again, and, luckily, the best ones founded this forum. I advise every newcomer to often use the "Forum Search" function and read the old threads from the early years. At that time the important characters were discussed thoroughly, and one can learn a lot! Meanwhile there are 2,690 forum members and lots of threads per day that, because of time constraints, often receive but a very short reply. Regards, Sundew |

Sincere thanks, Sundew, for your help and assistance once again. I appreciate your hints at useful sources very much and I'm definitely going have a closer look at the "Forum Search" function as soon as I find the time, but I'm also grateful to you and other experts for answering concrete and straightforward (though sometimes simple) questions so patiently. These expert opinions do not just help to satisfy human curiosity, but also offer very practical guidance to the newcomer and provide him (or her) with something like a shortcut into the giant diptera world, as you put it. One more comment on Tanyptera atrata: It's very rewarding to see what the chunks of wood from an old willow tree we left in the garden some years ago instead of using them as firewood are good for. Kind regards, Hans Theo K. |
