In one case, in the spring, we set up a set of concentric circles of traps, caught many flies in them, and marked them and released them at the circle center. After doing this for some weeks without getting a single return, we abandoned the experiment! Maybe the flies in spring are exceptionally motile, since in another smaller case we did get a few returns. I also caught some robusta at my home near St. Louis and released them a mile or so away, as I recall. I got a few returns. Research notes on such things would be among Stalker's and my research notes that are deposited at the American Philosophical Society archives in Philadelphia. Good recapture results were published for one of the Hawaiian species in Fontdevila and Carson 1978 Amer. Nat. 111:789-791. I suppose you have a copy of this.
