Unfortunately the attempt to catch it was unsuccesful but managed a photo before it flew off.
Chance of species ID possible despite few characters visible?
Vienna, late April

I thought about that species, but the dorsal streaks are much more pronounced in the photos of the specimen I saw.
Also,
T. albovittata hasn't been reported in Austria yet

I am now favoring
stigata/plebeja or maybe
marginula, not sure how the latter looks like.
The coloration of tergites and the wing are important, but having only this one angle and strong lighting, I feel it difficult to judge
