Thanks to Ian Andrews for suggesting Rhinophoridae in another place. I took it through Clemons' 2010 key to Rhinophoridae and Melanophora roralis is a possible. The wing pattern fits a female M. roralis and the halteres are dark. However, the cheeks below the eyes are supposed to be deep and they don't look deep on this one. Wing length 3 mm. Head and body length 3.5 mm. More pictures to follow.

You have to write something or the photo doesn't load.

Yes, that is a classical mistake. It is Catharosia (Tachinidae), which has a reduced postscutellum....... I guess it is C. pygmaea, check the colouration of both calyptrae Theo |

Thanks very much. The lower calypter is black, the upper colourless. Also, antennae all black and frons narrow, all characters of pygmaea according to S. Falk's 1998 article about the first British record.
