Researchers Discover 10 New Moth Species and 7 Genera Hidden in Hawaii Biodiversity Study
Scientists went looking for moths in Hawaiʻi and came back with 10 new species and major surprises.
Hawaiʻi is famous for its unique wildlife. But some of the islands’ most remarkable creatures have been flying under the radar — literally — and scientists are only now discovering they exist.
Researchers at the University of Hawaiʻi at Mānoa have identified 10 new species and seven new genera of Hawaiian leaf-roller moths, a discovery that highlights previously undocumented biodiversity in the islands. The study, conducted by graduate student Kyhl Austin and Professor Daniel Rubinoff, was published in Zootaxa in February 2026.
The newly identified moths include species with diverse characteristics, including some with brightly colored, iridescent wings. One species from Hawaiʻi Island may be the largest known member of its family.
Here’s what makes this find especially striking: while new species are regularly identified, the classification of a new genus is rare. Identifying seven new genera in a single study is considered highly unusual.
They crossed thousands of miles of open ocean to get here
Austin and Rubinoff conducted the research through the university’s College of Tropical Agriculture and Human Resilience (CTAHR), specifically its Entomology Section. The team used advanced “automontage” photography to create detailed, 3D-like images of specimens to support identification and future conservation work.
What they uncovered reshapes the scientific understanding of how these moths arrived in the Hawaiian Islands. According to the research, Hawaiian leaf-roller moths are among the most successful long-distance colonizers of any native Hawaiian animals. Evidence suggests they arrived through as many as 20 independent natural colonization events over several million years.
“Hawaiʻi is a world-renowned laboratory for evolution, but these moths have been hiding their true history in plain sight,” lead author Kyhl Austin said.
“By identifying these seven new genera, we are showing that these insects crossed thousands of miles of open ocean to reach Hawaiʻi far more frequently than we ever imagined.”
Names drawn from Hawaiian ecology and culture
The study does more than catalog new species. It reorganizes previously misclassified species and establishes new classifications to better reflect evolutionary relationships. Several of the newly proposed names draw directly from Hawaiian ecology and culture.
Leaf-roller moths are named for their association with host plants, and many of the newly identified species depend on the endangered ʻiliahi, or sandalwood. One newly established genus, Iliahia, is named after that very plant, which serves as a host for these moths.
A species within the Iliahia genus, Iliahia pahulu, is considered critically endangered. Its entire known habitat is a small grove of approximately 30 sandalwood trees on Lānaʻi.
Other newly described species include Paalua leleole, which exhibits a rare flightless form in females, and Iliahia lilinoe, named after the goddess of mists associated with Haleakalā.
Discovered — and already disappearing
The discovery carries an urgent undercurrent. Many of these newly identified species are already threatened due to habitat loss and declines in their host plants. Some species described in the study have not been observed in the wild for more than 100 years and are considered “presumed extinct.”
Professor Daniel Rubinoff called the discovery a “testament to what was here and what we’ve lost.”
“We are naming species just as they are disappearing,” he said.
Researchers emphasize that protecting the remaining species will require habitat restoration and the removal of invasive species.
Imaging the unseen
The automontage photography technique used in the study produced highly detailed visual records of the specimens, generating 3D-like images designed to aid in species identification. These images are intended to assist conservationists and researchers in identifying rare species in the field and supporting future biodiversity studies.
