I managed to breed the 2 Gray Tree frogs (definite Hyla versicolor) I collected in mid March. They've been living in the small exo terra terrarium with water in the bottom and lot of branches. They had become very tame. Anyhow, I put them in a small "I can't believe it's not butter" container for a few hours (at about 6pm) and then opened it at midnight. They were in amplexus. I then put them in a rubbish bin (standard size American Trash can) with about 12-15 cm (4.5-6 inches) of water, some very small fallen branches/twigs from the trees outside, and then placed them on a twig in there. I covered the top with a sheet of glass and put it where there was natural light falling on the top. At 7 am I checked and there were no eggs but they were still in amplexus. At midday there were many rafts of eggs in the water and they are still laying. I'm happy!
