OMG OMG OMG Grey Treefrogs Hyla versicolor

[Kurt]

I cannot confirm, nor deny that versicolor is the only gray treefrog that can be found in the Richmond area. However I am more comfortable with the assumtion that it is the only gray species there.
Yellow on the thighs is not versicolor specific and some specimens actually have orange rather than yellow.

My breeding male has yellow, my breeding female (from the same place) has almost no marking there, and my second male, also from a versicolor only area, is bright orange in that place.

So there you go. "Hyla versicolor is a tetraploid species, which means that it has two pairs of each set of chromosomes in each of it's cells. Cope's gray treefrog, H. chrysoscelis is a diploid species meaning it has normal chromosome pairs." - Me, upcoming gray treefrog article. That's true difference between the two species.
