This Drosophila-sized muscid (or Fanniid?) was caught on Ivy in Vienna, late September.

Second pair of images illustrate the follows: make photoof dry specimen or (worse)specimen in alcohol, but do not make photo of half-dried specimen!

Happy with my smartphone photo being sufficient for the ID.

The following two pictures where taken with a smartphone through a binocular microscope, with some disturbing light probably shining from the side (it was barely possible to distinguish the bristles on the shiny black body even when looking through the bino with bare eyes). However, the specimen was freeze killed and not in contact with EtOH, so the photos only give an impression of being 'half dried'
