[1] Udara blackburni is one of only two butterfly species that are native to Hawai'i, the other being Vanessa tameamea.

[3] The adults feed on flower nectar with their long coiled up proboscis.

The caterpillars are primarily found feeding on the Koa tree but occasionally on ʻaʻaliʻi, olomea, and māmaki plants.

Of the main Hawaiian Islands, the only two that have no records of these butterflies are Niʻihau and Kahoʻolawe.

[4] Native insects developed a lot of cultural meaning to Polynesians in the Hawaiian Islands.
