This frog was at least five feet above the ground, poised on a leaf, possibly waiting for the spider at the upper right of the first photo to move into a more lunge-worthy position. The angular ridges on the shoulders help identify this species as M. luteus.

Gephyromantis luteus is typically basically a solid color, but color variations occur also. The frog pictured here was one of my favorites from Masoala, due to its unbelievable camouflage in the leaf litter. I would watch it take a prodigious hop, and see exactly where it landed, but it would still take me several minutes to make out its form even though I was staring right at it the entire time. Then when I finally discerned its shape among the leaves I would set up my camera and it would leap again. This happened three or four times before I finally got decent photos.
