In April 1999 I collected in Budapest a male Rhamphomyia laevipes. I know that sometimes you may find strange variations in the wing venation. But this male had a very weird "modification". There were 2 "cross veins" between the M1 and M2, the first one, of course, closing the discal cell. The second one was parallel to the first one at a small distance. I never noticed it before. It is nevertheless not uncommon? thanks, ruud van der weele rvanderweele@gmail.com |

It happens frequently. Recently I have seen a empidine specimen that had it in both wings.

Hi, does it sometimes occur that crossvein (which closes the discal cell, Dm-cu) is lacking? I have some flies here (Empidoidea I assume) without discal cell, with a cell br, bm and cel cup, and vein M1 and M2 separate. The wing venation resembles mostly Opetiidae (like this: http://www.drawwing.org/insect/opetia-wing) Jonas |

There is Rhamphomyia anomalipennis that can have an open discal cell but you might also have a lok at Bicellaria.

Hi, I tried to take pictures (with my girlfriends Ipod trough the binoc).. Don't expect much  I assume the immense front legs are typical, but I cant find the species... I tried for family level, but I keep ending up with Hybotidae.  d2 by Jonas Mortelmans, on Flickr  d3 by Jonas Mortelmans, on Flickr  dipt1 by Jonas Mortelmans, on Flickr I found a second specimen, so the wing isn't an abberation Jonas |

You have Phyllodromia melanocephala (Empidinae, Hemerodromiinae).  I was thinking along the lines of Empidinae too much, did not realise it could have been Hemerodromiinae (or Tachydromiinae, for that matter). Had you mentioned the swollen fore femora, then it would have been easy.

Yes! I just found it myself accually (I have a male from another location, so it had to be common. It has truly gigantic genitalia, which makes it a bit easier). Nice one. Thanks anyway. Bye jonas |
