Solomon Island Leaf Frog

Solomon Island Leaf Frog


Found in the Solomon Islands and Papua New Guinea, Buka Island and Bougainville Island.


Found residing in the leaf litter of rainforests of tropical lowland and montane forests, where there is little standing water. This species tolerates a wide variety of habitats because of this; they may be found in degraded lands or rural gardens as well as in forests.


This frog is characterized by a triangular head, projections over its eyes and ridged veins under the skin of its back, giving it the appearance of a leaf. This species is polymorphic, meaning there are many different color variations. It ranges from gold, earthy browns to green in coloration.

These nocturnal frogs are ambush predators, meaning they sit and wait for prey to come into their vicinity before attacking. They are aided in this strategy by their coloration and shape which allows them to blend into decaying leaf matter on the rain forest floor, making it difficult for both predator and prey to spot them.


In the wild, this species appears to breed throughout the year, with loud calls that can be heard up to a half mile away. Males use their loud, bark-like call to attract females. After mating the female will lay five to 100 pea-sized clear eggs in small shallow pits dug out by the frog at the base of a tree. After about a month, the eggs will hatch into fully developed frogs measuring 1/8 inch in length.

Interesting Facts:
  • This species is also called the Solomon Island eyelash frog and Gunther’s triangle frog. The name triangular frog comes from the frog’s triangle-shaped head, and the projection above the eyes resembles eyelashes ? hence the name eyelash frog.
  • The male frog's loud calls sound like a dog’s bark and help them to mark territory and find mates. This call, like each frog species’ call, is unique to this species of frog.

The current population is abundant and stable; however, they are threatened by collection for the pet trade. The government of the Solomon Islands is considering passing legislation to stop the collection of this beautiful frog.

Did YOU Know?    
Unlike most frogs that have a tadpole stage, these frogs are one of the few species that do not have a tadpole phase. Instead, they hatch as fully developed baby frogs from pea-sized eggs.
