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.

I might add that this is a great resource and I am really thankful for all the members help.

Thanks for the explanation Paul. It definitely stopped me from flooding the forum with my threads Wink

Each user has a maximum of ten new threads per day (24 hours). Just to prevent a single user from sending scores of his unidentified fly photos at once and thus drain out any other threads.

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?

SabineH: you have to be logged in to see "New Thread" in the right upper corner of each "forum" site. In the case of accidental logout you have to start over.
