First I thought it was a common Dinera grisescens, but after a closer look at the photos I had my doubts about that ID. I cannot see a plumose arista, which is clearly recognizable in my other pictures of Dinera grisescens, and the scutellum tip is yellow. Also the colour of the proboscis differs. So I wonder who this fly may be - another Dinera species ore something else? Many thanks for help, Sundew Sundew attached the following image: [144.34Kb] Edited by Sundew on 18-09-2011 21:12

Female Solieria and Dinera grisescens seem easily confused in the field - until you check the arista. They both even have 2 pairs of scutellars Edited by ChrisR on 17-09-2011 23:27 Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London.

So which Solieria species could it be? Edited by Sundew on 18-09-2011 00:31
