Hypargyria metalliferella Ragonot, 1888 (Pyralidae)
Hypargyria metalliferella Ragonot, 1888 (Pyralidae, Phycitinae, Phyctini). There are very few records of this species and none previously on Springbrook Mountain plateau. It's common name is Silvered Knothorn — 'knot horn' presumably because of the crossed antennae at rest, and 'silvered' (argyria) because, unusually, the male is covered in brilliantly reflective silver scales under its wings. It's body length is 11.5 mm. The larvae are known to feed on leaves of Siphonodon australe.
The forewing scales are distinctively raised as a 'swelling' one third down from the base.
