Scorpion Fly male (Panorpa communis)

I am not sure of this fly's name, it was spotted in Bristol besides the River Frome.

I have been told that this image is of a male Scorpion fly, the orange part at the rear of the abdomen is a rolled up scorpion-like sting in the tail, this is only used by males to impress the females.

These flies are harmless to humans, they don't sting.

There are 4 different species of Scorpion fly in the British Isles.
