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
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 visitor to our garden, attracted in the evening by our moth light to our moth sheet. We hope its numbers will increase as we plant more of its rainforest foodplant trees. These trees, as they slowly mature, are converting our kikuyu paddocks back to their original rainforest habitat.
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 also differ.
