Overview

The Olaʻa banana hedyleptan moth is a species of moth in the family Crambidae. It is endemic to the Hawaiian Islands.

Omiodes euryprora faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited Hawaiian range. Invasive plant species have altered the native forest understory composition, reducing availability of its specific host plants. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and extreme weather events.

Threat summary

Habitat

This endemic Hawaiian moth inhabits native mesic and wet forests, particularly areas with dense understory vegetation between 300-1,200 meters elevation. It requires specific native host plants within intact forest ecosystems that maintain appropriate moisture levels and canopy cover.
