Moth antennae are threadlike and feathery and taper to a point. This differs from New Zealand butterflies, whose antennae are knobbed. These are the antennae of a female and male moth (Ichneutica ceraunias) compared with the antennae of a butterfly (Percnodaimon sp.). The genus Percnodaimon is presently under review by New Zealand entomologists.
