Video - My mistake

Ok, I thought the sound was from this beetle. I know it's a cricket sound, but I thought maybe I've found another little creature that gives away the same sound. But while filming I started to think it's impossible to "sing" so evenly and move so fast. And I've heard then the sound was coming from a bit more left. And after the climbing beetle left the sound was still there. :) So don't make the same mistake and don't think this beetle is so loud if you see it and hear a cricket at the same time. :)

And thanks to natalija's photostream I know now the ID of this beetle.
