I was reading that Hyla chyrsoscelis are prairie dwellers (at least where I live) and rarely will they enter the forest, so I have to wonder how many horizontal resting places they really need. Noted that mine sleeps in a horizontal position during the day, but sometimes on the back glass. Im thinking of setting up a terraium with tall orchid plants,as well as broad leafed pothos, as the orchids would at least kind of resemble prairie land plants in structure.
