I had a small swarm of Upwinged Flies in the kitchen yesterday. Yep, the kitchen. These were either Large Dark Olive (Baetis rhodani), Medium Olive (Baetis vernus) or Pond Olive (Cloeon dipterum) flies. It is probably a Baetis spinner though showing the large turbinate eyes.

I'm not an expert on flies and there are so many different types of these flies - what could they be exactly? No running water nearby, only my little garden pond out the back.
