Can someone identify these eggs?
That's an apple snail egg cluster. They're freshwater snails, and by placing their egg clutches above the water line they protect them from predation.

We actually have an issue with apple snails in Florida, because while the Florida applesnail Pomacea paludosa is native, three different invasive species have been introduced that are eating through native vegetation without many predators (1). 

Different species produce different colors of egg mass, and a good example of the green egg masses includes Pomacea haustrum, the titan applesnail, which is present in the continental US, but actually native to Bolivia, Brazil and Peru (2, 3). Since other species also produce green eggs, it's difficult to tell exactly what snail produced those, however.
