This will work in Florida if you use Darsie and Morris's "Keys to the Adult Females and Fourth Instar Larvae of the Mosquitoes of Florida" (1)

Once you have this to genus:

ID: hindtarsomeres with pale bands->2
Hindtarsomeres with pale bands apically and basally, at least on some segmnents->9
select Oc. canadensis canadensis as 5th tarsomere entirely pale-scaled.

OR in (2)
1-2-28-31-32-33
The salient ID features evident in this photograph are:golden-brown scales on scutum, tarsomeres with pale rings apically and basally, scutum without dark median stripe, scutum without lyre-shaped pattern of golden scales and that's about it. So keying it requires 3 steps with the local guide and 6 with the North American guide. If one becomes familiar with species in one's area, ID's can go much easier, but mosquitoes in general require some effort to ID.
