Hi, Yesterday (a very warm day) I saw many small dark flies quickly running on some erratic boulders that were placed along a park way. While running, they waved their wings just like in the video by Rui Andrade (https://www.youtu...bZG15xbHRk). When two met, they closely circled each other and jumped on and off at high speed. Very short phases of resting made taking pictures difficult. The darkened wings were conspicuous. I think they might be Periscepsia carbonaria, the species is said to occur in the Berlin region. Experts’ opinion is appreciated, however! Thanks in advance, Sundew Sundew attached the following image: [285.23Kb] |

In this set of photos I marked the short bristles I consider to be discal ones with an arrow. There seem to be three humeral bristles forming a triangle. On the scutellum there are two erect bristles. - The late time of the year would also fit.
