As APS suggests sand fleas,flies, no-see-ums, etc are tiny. Generally speaking, the bites trigger an allergic reaction to them and Florida residents usually become immune and are not bothered by them. Newcomers can have severe reactions including large blisters.
It is also true that there is a geographic variation even in Florida and not all “sand fleas” are the same.
I had no idea Florida entomology was so fascinating in the Lakes Region.
Now, about duck itch and black flies....
