This mosquito (thankfully a male, note the plumed antennae) is Culex erraticus, no common name. It is widespread over the southeastern United States, and while in Florida the females primarily bite birds and reptiles, they do of course also feed on mammals and also on people (usually me). They actually generally feed on birds during nesting season, then, when the young birds leave the nest, C. erraticus move on to other hosts.

There’s actually a lot known about C. erraticus, because they are able to transmit Eastern equine encephalitis virus (among other diseases) after biting infected birds.
