Observation notes: Flying somewhat like a butterfly which it resembles, but the feathered antennae says otherwise.
Habit was flying slowly low; interested in grass and occasionally alighting on wooden deck.
Early morning cloudiness, light breeze, dry, cool.
Very difficult to see dorsal side of wings; only one image showing same, but out of focus, caught in flight.
Other images shown some of the dorsal wing features with moth at rest.
