This fly looks a bit like the black and yellow Sciara hemerobioides that has been posted on iSpot a few times, but that species has black legs, whereas this one has very distinctive white 'feet' that are particularly obvious in flight. I know very little about Sciaridae, any identification suggestions would be welcome.
