Yes, I agree that the ultrasonic rubbing sounds originate from one of
the numerous bush cricket species. Unfortunately, I don't know exactly
which species it is. I remember that I also captured those sounds
while recording bat echolocation calls in Greece a few years ago.
There are a lot of bush cricket species that emit similar rubbing
sounds, such as the European Wart Biter (Decticus verrucivorus):
