Located about 2,300 miles (3,680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of at least 5 million years. As a consequence, Hawai'i is home to a large number of endemic species. The radiation of species described by Charles Darwin in the Galapagos Islands which was critical to the formulation of his theory of evolution is far exceeded in the more isolated Hawaiian Islands.
Laysan is one of the Northwestern Hawaiian Islands, located 808 nautical miles northwest of Honolulu. It comprises one land mass of 1,016 acres (4.11 km2), about 1 by 1+1⁄2 miles in size. It is an atoll of sorts, although the land completely surrounds a shallow central lake some 2.4 m (7.9 ft) above sea level that has a salinity approximately three times greater than the ocean. Laysan's Hawaiian name, Kauō, means 'egg'.
The Laysan millerbird was a subspecies of the millerbird, similar in appearance to the remaining subspecies, the Nihoa millerbird. Its dorsal side was brown, and its belly was grayish. Its name derives from its favorite food, several species of moths of the genus Agrotis commonly referred to as "millers".
Agrotis is a genus of moths of the family Noctuidae. The genus was erected by Ferdinand Ochsenheimer in 1816. A number of the species of this genus are extinct.
The Laysan noctuid moth is a species of moth in the family Noctuidae.
The Procellaris Agrotis noctuid moth is a species of moth in the family Noctuidae.
The Laysan dropseed noctuid moth was a species of moth in the family Erebidae. The species was first described by Otto Herman Swezey in 1914. This species is now extinct.
Oodemas laysanensis, the Laysan weevil, was a species of beetle in family Curculionidae. It was endemic to the United States.
Agrotis panoplias, the Kona agrotis noctuid moth, is a species of moth in the family Noctuidae. It is now considered as possibly extinct.
