This female Eastern Dusk-Flat also came to our moth light, Claire Cottage Dorrigo, 8 Jan 2018 9.45pm. She measured just under 80 mm wing tip to wing tip sitting as in this photo.
Unusual view of a variant Eastern Dusk-flat (Chaetocneme beata) Claire Cottage Dorrigo, 20 Dec 2017, 8.10 pm - identified by Kelvyn Dunn - note its red eye.
Nearing dark on 20th Dec 2017, we observed an Eastern Dusk-flat feeding on Buddleia flowers. Occasionally it fluttered its wings continuously in the way Hawk Moths do when preparing to fly. Interesting to see this butterfly so relaxed hours after other butterflies had ceased flying.
Breeding season on the Dorrigo Plateau: Thought to be September to April. We have also had adults attracted to light 16/12/19 @ 20.15 hrs, 17/12/19 @ 20.00 hrs and 19/12/19 @ 20.30 hrs.
Flight habit: Crepuscular (becomes active at twilight) resting throughout the day on the underside of leaves.
Habitat: East Coast often near Rainforest - subtropical, warm temperate & littoral and in urban areas.
Items of Interest: A rare sighting in our garden, attracted in the evening either to our moth sheet by our moth light or to our Buddleia flowers by their strong scent. We hope to see more of these special butterflies as their numbers increase due to more rainforest larval foodplant trees being planted close to our cottage. These young trees, which are slowly maturing, are converting our kikuyu paddocks back to their original rainforest habitat. Our evening sightings in Dec 2018 & Jan 2019, were of two butterflies at the same time, on the same buddleia, both in sight of each other but feeding on separate flowers.
Eastern Dusk-flat larvae after emerging from their egg cut out a piece of leaf and fold it back to form a shelter on the leaf surface. More mature larvae form a shelter by attaching two leaves together. Larvae stay in these shelters during the day and come out to feed at night.
The Eastern Dusk-flat rests on flowers and leaves with its wings open. It's red eyes distinguish it from the Bronze Flat. The white wing markings seem to differ in each specimen.
