A group of flies were dancing a few cm above the water in a stream (Catalonia: La Garrotxa: Beuda: Riera de Rajolins, 11/05/2013). I trapped some of them with a net, so they got wet. Are these male and female of Empididae? Are them specifically of river habitats?

Not far from there, there was another one, that could be the same family. It was about 6-8 mm.

Hilara. Males usually have swollen fore tarsi. Some species swarm low over water. |

Many thanks, John, I see there is a lot of species (so the last one is a female?) |
