Mythimna amblycasis is a moth of the Noctuidae family. It is endemic to Kauai, Oahu, Molokai, Maui, Lanai and Hawaii.

Larvae feed on various grasses, bunch grass and sugarcane. The caterpillars become full-grown in about a month from the hatching of the eggs. The full-grown caterpillar is about 38 mm. It is usually cream colored with pale brownish mottlings.

Pupation takes place in an earthen cell a little below the surface of the ground, or beneath stones or rubbish. The pupa is about 19 mm long and 5 mm thick. The moth emerges from the pupa in about two weeks.

Adults have been reported feeding upon the blossoms of Metrosideros species.
