Bronze Flat (Eastern Flat) Netrocoryne repanda repanda
Wingspan: 39 - 41mm
(Note two subspecies are known: (Netrocoryne repanda expansa) & (Netrocoryne repanda repanda)
Distribution: Cape York Peninsula & FNQ (Netrocoryne repanda expansa) Central QLD through NSW to eastern VIC (Netrocoryne repanda repanda)
Status Claire Cottage: Initially uncommon, slowly becoming more common with at times more than one seen together.
Status elsewhere on the Dorrigo Plateau: no sightings to date.
Butterfly Sightings:
Larva Sightings:
Larval Food Plants:
Breeding season on the Dorrigo Plateau: Thought to be September to April
Flight habit: Throughout the day but more active early morning and late afternoon.
NSW Habitat: East Coast often near Rainforest - subtropical, warm temperate & littoral RF and suburban gardens.
Habitat where found at Claire Cottage: Rainforest edge
Items of Interest:
Initially an infrequent visitor to our garden but a butterfly that is increasing in numbers at Claire Cottage as our planted rainforest trees slowly mature helping return our kikuyu paddocks back to a natural rainforest habitat.
Bronze Flat larvae when young cut out a piece of leaf and fold it back to form a shelter on the leaf surface. More mature larvae shelter in rolled dead leaves. They stay in these shelters during the day and come out to feed at night.
The Bronze Flat can be confused with the Common Red-eye but lacks the red eyes. It rests with its wings open providing opportunity to check its white markings which differ from those of the Common Red-eye.
In March 2021 at Hornsby Gary Harris discovered two larva feeding on Camphor Laurel, this is the first recording of this larval food plant.
