Willow Pond does have green frog tadpoles, thanks. And thanks for the advice about the bullfrogs, something I have already experienced. My last pond had leopard, green and bull frogs at first. Eventually all there was were two fat bullfrogs. After moving from Illinois where green frogs are plentiful to Nebraska where they seem to be missing, I needed to get some. They stay in/near the water and the leopard frogs wander far away, so they don't really compete for the same food. Plus they are very tame in my experience, sometimes eating crickets right out of my hand. I actually watched one of the big bullfrogs at my provious pond eat a sparrow that got too close! I will be happy when my shipment of 50 tads arrive.

Looks to me like a regular green frog... not a bullfrog as the ridge of skin goes straight down the back. I see no evidence of the spots that a leopard frog would have. Bullfrogs and green frogs can be hard to tell apart if you can't get close - but leopard frogs and green frogs are quite different so they're not as usually mistaken for one another. He's cute!

They are both juvenile Gray Treefrogs. However, there are two identical species of Gray Treefrog in Michigan - Gray Treefrog (Hyla versicolor) vs. Cope's Gray Treefrog (Hyla chrysoscelis), but the more widespread species is the Gray Treefrog (Hyla versicolor). They can have varying amounts of green, particularly when small like that. I would call these Hyla versicolor. If you have heard the adults calling, you can tell them apart.

Wow that's a gorgeous tray Bebe. My SIL would LOVE it. She's a frog collector. Green is her favorite color! ha They look so darling, like they are just playing around having a good time. We used to play with the little green frogs like that back home when we were little. =) ~Anj
