We found a tree frog at the bottom of a pallet of potting mix bags. I relocated him to our indoor butterfly house. There currently are no butterflies in the house since we only have them for a couple months each year.
Unfortunately, I found out that these guys can eat 2 or 3 butterflies a day during the exhibit. We think there are up to 6 tree frogs in the butterfly house, so that means 12 to 18 dead butterflies a day. The butterflies cost somewhere around $5 each (we buy the chrysalis), so that's a lot of money! I think we're going to have to try to hunt down all the tree frogs in the next couple weeks and relocate them.
