Polkadot Treefrog (Hypsiboas punctatus)
This photogenic treefrog spent its nights perched on the grassy blades of an outdoor potted plant at Uakari Lodge. This was a popular frog hangout; on other occasions this same plant sported a Common Bromeliad Treefrog and a Greater Hatchet-faced Treefrog (no, really!).

Here is an account of the four days we spent at Uakari Floating Lodge in the Mamirauá Sustainable Development Reserve.

Polkadot Treefrog (Hypsiboas punctatus)
This more lightly-colored frog was on the same plant a couple of nights later. It might be the same individual though, because the orange/red color on the backs of these frogs becomes more pronounced at night, and this photo was taken a couple of hours earlier in the evening than the previous one.

Polkadot Treefrog (Hypsiboas punctatus)
This beautiful species is widespread and common in the Amazon basin. We found this one on the road from Iquitos to Nauta at night, while we were (mostly unsuccessfully) looking for snakes.

Here is a complete list of the herps I saw in the wild on my 2013 MT Amazon Expeditions trip.

Hypsiboas punctatus was among the many species of frog that have made a happy home in and around the pond at Santa Cruz Forest Reserve following the damming of a creek in order to form a steady source of water for the field station.

The next year, a few pretty Hypsiboas punctatus were mixed in among the many Dendropsophus triangulum around the Santa Cruz pond.

Polkadot Treefrog (Hypsiboas punctatus)
This young Hypsiboas punctatus is not actually in danger from the giant menacing stick monster, but I can't blame it for looking a little nervous.

On our last night in Peru for 2016, I saw one last pair of Polkadot Treefrogs: one colorful adult and one little bitty metamorph.
