I suspect that this fly might belong to the genus Lispe. If that’s the case, I don’t think these photographs show enough detail, especially of the leg bristles, to use the Snyder key (1).

These flies have been fairly common in this intermittent “stream” leading to a small drainage control pond and the bright white palps make them easy to spot. The flies are fairly skittish and hyperactive, and they’re hard to get near. I didn’t see any actual predation but they did appear to make attempts at nabbing flies of other species.

I’d appreciate confirmation or, more likely, correction of that “ID”. Thanks in advance
