Udara blackburni is also known as the Koa Butterfly. It is one of two butterflies that are native to Hawai'i. These butterflies have outer wings that are blue, while their inner wings are green and they are only about an inch in length.[1]
These butterflies have a wingspan of about an inch.[1] The upper sides of their wings are blue and they usually display their wings upright to show the underside of their wings which are green.[2] They feed on the flower nectar with their long coiled up proboscis but the caterpillars feed on the Koa tree and the ‘a'ali'i, olomea, and mamaki plants.[2]
This species is endemic to Hawai'i and can be found on the islands of Kaua'i, Oahu, Maui, Molaka'i, Lana'i, and Hawai'i Island. The only two islands that don’t have these butterflies are Ni'ihau and Kaho’olawe.[3]
Native insects developed a lot of cultural meaning to Polynesians in the Hawaiian Islands
