Great advice above. Yep, you have yourself a cute little green tree frog (Hyla cinerea).

You can also use a glass food bowl for her crickets. You will need some amphibian/reptile calcium with vitamin D3 powder and some amphibian/reptile multivitamin powder. Gently dust your crickets every other day and once a week with the multivitamin powder, but not on the same day. A baggy works best...put a little pinch in and gently shake the bag...like shake and bake, lol! Just so they're lightly coated. Their crickets or food should be no larger than the distance between their eyes. They like live food and their feeding response is triggered by the movement of the bugs.

I'll add more in a bit. Getting my hair done .
