Longhorn bees are very hard to determine. This could be either E. longicornis or E. nigrescens. Both are known in Austria.
A user on Facebook suggested E. nigriscens: facebook.com
These 7 male Langhorn bees are taking a break together on Salvia. The reason why they are gathering in this image is for me unknown.
