The undiscovered small beetles in the tropical rainforest are probably endless. But that did not discourage citizen scientists on expeditions to the Ulu Temburong forest in Borneo to keep adding them to scientific records, one at a time. Together with a team of researchers, they published a new ‘little things that run the world’.

Clavicornaltica mataikanensis, named for the stream Mata Ikan (“fish eye”) that runs in the valley where it was found, is one of a plethora of tiny beetle species that live in the leaf litter of tropical forests—and most of them have not yet been scientifically described and named. At 2 mm long, the flea beetle is actually one of the largest among its relatives – which might explain why so little is known about their ecology and diversity.
The field trip, in which local students and researchers also took part, gave untrained lay people the opportunity to participate in the study of this hidden world of biodiversity and in the process of naming and publishing new species. Participant Lehman Ellis, from the US, says it was “exciting and beautiful” to be part of the discovery.

Entomologist and founder of Taxon Expeditions, Dr. Iva Njunjić, says: “We introduce the general public to all these tiny, beautiful, and completely unknown animals, and show them that there is a whole world still to be discovered.”
