One of the many tree frogs that live in our house. We have a little thriving colony which hides under the flooring( which is a linoleum slightly heavier that wallpaper and not glued down.) Occassionally they make a little croak but we have gotten used to that. I think that they, along with the cameleons, eat many of the bugs including the cockroaches, so we are most content with their presence. If you surprise them, in the middle of the day after being out for awhile or in the middle of the night, they are cavorting all over the place, on the walls, the furniture, and in this case trying to hide on the top of a glass.
