Megalorrhipida leucodactyla (Fabricius)

White-footed Feather Moth (Megalorrhipida leucodactyla)

The White-footed Feather Moth has a pantropical distribution, that means it occurs in the tropics worldwide, thus it probably occurs naturally in some parts of Polynesia as well.

The caterpillars are not specialized to any host plant species and feed on a wide range of plants, including the widespread species Boerhavia albiflora Fosberg, Boerhavia repens L. and Boerhavia tetrandra G. Forst..
