I can only identify this as a fly with cool striped eyes. I'm not an expert on insects and to obtain an exact ID even experts usually need to examine an insect's genitalia. Yes, that's true, and I only brought it up because you asked. Like with all the pics here feel free to click on the image to get a better view.
Loyal readers will know that I recommend Bug Guide if you ever have a yen to ID an insect. Be warned however that there are thousands and thousand of species, so trying to figure out what you've seen can be exercise in frustration.
