from my post from some years ago,
I have learned that this rute is chararcteristic for Tanytarsini
Here is suppsingly another species from the same site, swarming in numbers some 10 days ago, but "propelling" by wings rather then gliding on the surface. Possible sp. identification?
(of course not Asilidae bu I can not change the place by edit)

Were these found near salt water? They look like Telmatogetoninae to me.

There are a few Orthocladiinae adapted to ground (or water surface) mating. These show the typical non-swarming adaptations, with reduced antennae, short legs, and enlarged hypopygium (see shadow at left of first photo).

The low front leg ratio rules out Tanytarsini and the wings are consistent with Orthocladiinae.
