Underwing from Fiji

Moth in Fiji
Hello, we saw this moth on the door when we returned to our Fijian bure
(thatched hut!) at night. Can you identify it please?
Thanks, Sarah

Hi Sarah,
Tropical species are not our forte, but your moth bears a resemblance to a genus we have, Catocala, known as the Underwing Moths. These moths generally have drably colored upper wings and gaudily colored underwings. They are nocturnal and rest during they day on trees and similar places where they are well camouflaged. If startled into flight, they attract attention, and the pursuer, a bird or other predator, will be looking for the colorful tasty treat, but when the moth lands, it once again blends in.
