Sure looks like a Leopard frog to me. I found that my largest bullfrogs come out at dusk, just when the solar lights come on, and the 2 or 3 of them have favorite spots to sit on the edge of the pond, just under some light or another. So, try going outside at dusk, with a flashlight, and see what you can find! Totally different world out there at night. Spiders are busy spinning new webs, they love it when you shine a light on their web, as a moth is likely to come to the light, and be an easy meal for them. My young bullfrogs are mostly pretty easy going. I went into the ponds last weekend again, and there were times they were less than 12" from where I was standing, and considering I was pulling old lily leaf stems off underneath them, that's pretty tame! I talk to them so maybe that helps. They know me. And, I occasionally toss them a small grasshopper. I sure have plenty of the grass hoppers, but most of them are getting pretty large, too large for the young bullfrogs, but perfect for the big ones. I have a few leopard frogs, but they are VERY skittish, usually outside of the ponds, and jump into the overgrown bog for shelter.
