Neat, Glen. Thanks, I'll try that with my grandkids next time they visit. Not too many frogs in Utah where they live, but they love all the wildlife here. I have many sweet little peeping tree frogs that make a lovely chorus at night.
I can usually (but not today
) find a Cuban Tree frog or two in the daytime as I have had traps set out for them for years now. They are a very destructive invasive species here, so the University of Florida frog boffins recommend they be trapped and euthanized to preserve the native species. Since I have a very attractive habitat for frogs here, with my fish pond I had a large population a few years ago.
Here are my "traps" - lengths of PVC pipe stuck vertically into the ground. The angled cut end digs into the soil easily. The frogs love to sleep inside them through the day. If it's cold they will be way down near the ground but if warm, they are up inside the pipe, very easy to see. I've never seen anyone but the Cubans in these, but I imagine other frogs might find them attractive hiding places, too.
