The head is not in focus in any shot, but tergites and legs might provide crucial characters. I went backwards and tried to exclude as many species as possible - and now am left with M. grisea and M. tenebricosa (but might have overseen something). The bristles on the mid tibia are well visible, but I am unsure about their exact position. So, if the character combination: "1 ad on mid tibia + tergite 3 with complete row of marginal bristles" vs. "mid tibia with 2 - 5 ad. + tergite 3 with 2 - 4 dorsal marginal bristles" can be resolved, a species ID might be possible. Observed in a garden in Vienna End of April (early date should also excxlude some) enlarged image: Edited by Carnifex on 24-09-2019 08:42 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.
