This is R. campestris which darkened abdomen edge and rather dark legs. If you have an idea about genus and perhaps species, google for literature (e. g., the Rhingia key http://web.archiv...n_key.html) or search the older forum threads (in this case Forum Search - kewords Rhingia - sort Ascending) - it is a treasure! In the threads of the first years of the forum you get lots of information about discrimination between species.
