Javelin frog

The javelin frog, pygmy rocket frog or cairns tree frog ("Litoria microbelos") is a small frog from northern Australia. It lives in northern and central Queensland and in Kimberly.
The frogs are less than 2 cm long, some of the smallest in Australia. They are light brown with dark brown stripes.
They lay eggs in areas that are temporarily flooded and not in permanent bodies of water like ponds. Adults hide in the grass or under rocks or logs.
