Sugarcane Bud Moth (Erechthias flavistriata)
This species was described in the year 1907.
The larvae are known to feed on a wide range of plants including Coconut Palms, Screwpines, but also cultivated plants like Bananas, Pineapples, and Sugarcane.
The species may actually originate from Melanesia and may have been introduced to Polynesia accidently by man.
Entwined Fungus Moth (Erechthias strangulata)
The Entwined Fungus Moth was described in the year 1929 on the basis of material that was collected on the Fakarava atoll, however, the type specimen is practically denuded, lacking any scales on its wings, which again are highly damaged, the abdomen is missing, the thorax is merely a sceleton. 
The species is so far known only from the Fakarava atoll and may indeed be endemic.
