Laysan Cutworm; Miller; Miller Moth
(Agrotis laysanensis)

 
syn. Prodenia laysanensis

 
distribution:

Hawai'i Islands: Laysan

 
local name: -

 
size: ca. 3,5 cm (wingspan)

extinction date: last seen in 1911

 
Unfortunately nothing is known about the habits of this species, which occurred apparently only on the island of  Laysan.

~~~~~~~~~~~~~~~~~~~~~

The guano collectors, who occosionally stayed at the island, named these moths 'Miller', a term, that is used in the English-speaking area for all more or less brownish or greyish coloured moths.

The Laysan Cutworm was probably the main food resource for the also extinct Laysan Reed-Warbler (Acrocephalus familiaris familiaris), which again was named owing to this fact as 'Millerbird' in English.
