Sorry, more than
Thereva spec. is not possible for this couple. The lower picture shows the male, and
Thereva males cannot be told apart from a photo. The upper female nicely shows the black spot between the eyes, but we need to see more characters, one picture is not enough. Compare the key
https://home.hccn...ml#Thereva to understand which are the decisive characters to identify
Thereva females (at least colour pattern of the tergites and haltere colour).
Regards, Sundew

Thanks a lot. Unfortunately, I only have one picture of this pair.
I had a similar fly in thread https://www.diptera.info/forum/viewthread.php?thread_id=39894. There are more details.
