Agrotis crinigera Butler, 1881

Poko noctuid moth, Larger Hawaiian cutworm



Taxonomy & Nomenclature



Conservation Status


Last record: 1926

IUCN RedList status: Critically Endangered (Possibly Extinct)


"This species is now thought to be extinct since it has not been collected for more than 90 years.  It has been recorded from Laysan, Kauai, Oahu, Molokai, Lanai, Maui, & Hawaii Islands. It’s common name is larger Hawaiian cutworm (“Poko” mo) and has a C3 endangered status. Zimmerman (1958) lists legumes as it’s host plant as well as Datura. Little is known of it’s current status and it is likely this species will not be rediscovered. I do not believe A. crinigera to be important to the overall health of Laysan unless it can be found again. Searches on the high islands have proved unfruitful."
