Borneo Flying Frog

Rhacophorus borneensis

Borneo flying frogs spend their lives high in the humid canopy of pristine dipterocarp rainforests, descending to lower vegetation primarily to breed. Using extensively webbed feet and lateral skin flaps, they glide effortlessly between tree trunks and foliage in search of prey. Females construct suspended foam nests on overhanging leaves above forest pools, allowing newly hatched tadpoles to drop directly into the water below.

What to notice
Look for vivid green dorsal skin bordered with intricate black-and-yellow lateral markings and broad, fully webbed hands and feet.
Support conservation
Observe entirely hands-off from trail margins and avoid touching the skin or disturbing fragile suspended foam nests.
Responsible observation
  • Spotting Location: Search dense vegetation surrounding clean, standing rainforest pools after heavy dusk rains.
  • Lighting Caution: Use low-intensity red headlamps to inspect foliage without startling active gliders.
  • Habitat Protection: Avoid shaking low branches or disturbing foam nests attached to leaf undersides.
