Treefrog

hyla2
We've had a lot of treefrogs (Hyla) this summer. I found this one perched on the leaf of an orchid this afternoon.

Another view from an oblique angle:

I had always assumed that these frogs are Hyla versicolor, the grey treefrog. But there is an interesting complication as noted here. H. versicolor has a sibling species Cope's grey treefrog, H. crysoscelis. H versicolor is tetraploid (4n=48) but H. crysoscelis is diploid (2n =24).
