The smallest frog in the Asia, Africa and Europe and one of the world's tiniest was discovered inside and around pitcher plants in the heath forests of Borneo. The pea-sized amphibian is a species of microhylid, which, as the name suggests, is composed of miniature frogs under 15 millimetres long.

The discovery was made by Drs. Indraneil Das and Alexander Haas of the Institute of Biodiversity and Environmental Conservation at the Universiti Malaysia Sarawak, and Biozentrum Grindel und Zoologisches Museum of Hamburg, respectively, with support from the Volkswagen Foundation. Dr. Das is also leading one of the scientific teams that is searching for the world's lost amphibians, a campaign organized by Conservation International and IUCN's Amphibians Specialist Group.
The mini frogs (Microhyla nepenthicola) were found on the edge of a road leading to the summit of the Gunung Serapi mountain, which lies within Kubah National Park. The new species was named after the plant on which it depends to live, the Nepenthes ampullaria, one of many species of pitcher plants in Borneo, which has a globular pitcher and grows in damp, shady forests. The frogs deposit their eggs on the sides of the pitcher, and tadpoles grow in the liquid accumulated inside the plant.

Adult males of the new species range between 10.6 and 12.8 mm - about the size of a pea. Because they are so tiny, finding them proved to be a challenge. The frogs were tracked by their call, and then made to jump onto a piece of white cloth to be examined closer. The singing normally starts at dusk, with males gathering within and around the pitcher plants. They call in a series of harsh rasping notes that last for a few minutes with brief intervals of silence. This "amphibian symphony" goes on from sundown until peaking in the early hours of the evening.
