Just a guess: Ocyptamus

DO you have a shot that shows the abdomen (shape, pattern) more clearly? (I'm not sure this fly can be IDed from a photo, plus there are syrphids peculiar to Florida as a further complication.)

Two things
I agree, Syrphidae. Two things to help distinguish flies and wasps: Wasps typically would have longer antenna. More trustworthily, you can just barely see a whitish-yellow haltere sticking out from where the wings attach to the thorax (one on each side). Depending on the pose, these little vestigal wings are often easy to see and can quickly eliminate the possibility it is a wasp.

Haltere-like structures sometimes on wasps
True halteres always distinguish flies from wasps; however haltere-like structures occur on some extremely tiny wasps. These include the Mymarommatidae, which are missing from bugguide (probably because they're so small). See here for a more detailed explanation.

Note: For a specimen of this size the presence of anything that looks like a haltere will always exclude a wasp.

Syrphid of some kind I believe. The experts will be able to tell you more.
