General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~40mm wingspan. Males have bipectinate antennae, reducing to filiform about 3/4s along. Females have fully filiform antennae.
They have a thick black stripe running throught their face, that generally goes unnoticed. But when it's pointed out becomes very obvious.
When on a window, with a lite backdrop, their underwing patterns show through.
Their dorsal patterns/black lines can be very weak. A number of specimens are shown here to show the variation.
Their ventral patterns are what they are named after, with red lines and black blotches that need to be seen to be appreciated.
We have photographed 7 specimens (1 female, 6 male), in Nov, Mar, Apr & May.
