hi Flyforum, Yesterday I found this fly in some grass and Brassica napus. It is a elegant fly, the wing is long-oval shaped. Black thorax with some strong black or dark hairs. The legs are yellow/braunish and the arista is fine and long. The fly was about 4-5 mm What fly is this?  greeting, Robert |

Hi Robert, It is a female Lonchoptera (Lonchopteridae). I don't have the literature for identification to species level at hand now, but I will try to give you a species name later. Jan Willem |

Hi Robert, I think it is a rather dark specimen of Lonchoptera lutea, but I have to admit that I am not sure about it. Jan Willem |

Yeah, one of my little frustrations is that i've never been able to find other species than L. lutea and females of L. bifurcata (in the NL). The latter species is parthenogenetic, at least in GB and the NL. L. bifurcata has pale vertical britles, pale basal segment of antennae, and partiall dark potocular cilia (Smith '69), so most likely it is a dark specimen of L. lutea as JW said. cheers, Louis |
