5-7mm long - garden, Flensburg, Germany. On an old radish plant which keeps on flowering even though it has some mature seed pods. There were 5 to 10 Sepsidae on the plant. Most were fairly active, running around and flying from one leaf or flower to the next. This one, however, was comparatively passive. I photographed it between 15.05pm and 15.34pm. In all this time it had a bubble at it's mouth and remained in the vicinity of one flower; at first on the petal, then onto the flower stem where it excreted liquid from it's abdomen and it wiped of with it's hind legs, then it wiped/massaged it's thorax and wings then returned to the petals. Video of it wiping off the rear droplets and it's wing:- https://www.youtu...qlyGqueB9w Ray Perry attached the following image:  [136.43Kb] Edited by Ray Perry on 21-10-2017 14:28 |

The last photo hints at a notched fore tibia so it might just be S. cynipsea. Would it be possible to enlarge the area around that leg?

Thanks Steve. Here's a good image of the legs, taken at 15.09pm. Does this show the notch you're talking about? Does the notch also imply that it's a male? Ray Perry attached the following image:  [59.92Kb] Edited by Ray Perry on 20-10-2017 22:03 |

Thanks Ray, cynipsea looks likely with this one.
