Hello Forum,

again a species from the (artificial) alder marshland in Hagen (Germany), 175 above see level. The photograph attached I took on September 15th 2007. The plant in the background is Rubus fructicosus agg. (i.e.: Rubus vestitus) My hope: the picture is good enough for identification.

Maybe the fly is a member of the family of Lauxaniidae?

Thank you for your help.

Best regards,

Josef
