Can anyone tell what this is? I spotted it patrolling the lily leaves in my garden pond. The apparent object of it's affections was a smaller fly with same colour body but no wingtip "flashes". As it approached what I take to be the, smaller, female it would flash it's wings by displaying them at right angles to the body. I don't ever recall seeing a fly with these markings before.

Your assumptions RE male and

Your assumptions RE male and female and courtship behaviour are correct. I think this is the only species of this form with white wing tips like this, but I'm not 100% certain.

Thanks for that. Having now looked up your suggestion, it seems to fit what I observed admirably.
