Northern Germany, Schleswig-Holstein, Schenefeld near Hamburg, walking path along the rivulet Düpenau, on a wooden case, called "Hotel for Insects" where especially bees fly in and out. Length of the fly 5mm; 9th of May 2021, Photos: kuv.
I watched a fly first waiting before a bee hole, then going backwards in the hole. I think it is a parasit of bees. Please help to get the ID.

Name correction: Cacoxenus indagator Loew, 1858 (not indigator), Drosophilidae, with senior but by ICZN suppressed name Domomyza cincta Rondani, 1856. Long time Domomyza Rondani was treated in Agromyzidae. Read: Deeming, J.C. 1988: The Identity of Domomyza cincta Rondani (Diptera): Drosophilidae not Agromyzidae. - Entomologist's monthly Magazine 124: 81. The species develops -partly in masses- in cells of solitary bees.
