Reddish wave

That pbase link seems to include a community that has various universities and butterfly societies which were tapped into for the identifications to his images.

very embarrassed. I went to sleep without passing all that on to you. Also the Brian on Pbase who did the id is very well connected. I sent an email and had an answer and trust the identifications on his site

I have the same moth with the same colour underwing as well as one with a plain underwing. I have also not given it an identification because I cannot find one with the reddish tint. I have taken your lead and called it Scopula sp. http://www.projectnoah.org/spottings/17614296 I have several spottings of the reddish underwing and the plain underwing and I believe the reddish tinge to be on the wings not a reflection

Geometridae - Sterrhinae Waves There are several to pick from but its confusing. The color in the underwing is not seen so I wonder if yours was a function of reflected light? If I was pressed to guess, I think you have the varied wave Scopula optivata but not confident to call it. At lease you can look further. My reference is Peter Marriot again (part 3) http://www.iffa.org.au/moths-victoria-peter-marriot
