This specimen clearly has two stripes, the first along the costa is what I would call orange, the second is white and this leads into the grey forewing. The controversy seems to be what the colour of the first streak is. If it is yellow followed by white followed by grey, is it P. bicosta? If it is white only streak leading into grey with a yellow head = Palaeosia sp. If it is only white streak leading into grey with a grey head = female Scoliacoma nana.

OK, having looked at the side-on view of this sighting I can concede this one is probably P. bicosta because there is a light orange and cream streak along the costa. Moths of Victoria recognise two other speciees Palaeosia sp.(1) and Palaeosia sp.(2). Both of these have lighter not cream costas. P. sp(1) has a thin yellow streak bordering the light costa and a yellow head and collar (front of the thorax). So no, I would say a yellow and white costa is not P. bicosta, but Palaeosia (genus) in our terminology. Therefore thats why I say sighting 4430960 is Palaeosia (genus) as is 4430972 also. Palaeosia sp.(2) is described as having a thin black edge at the leading edge of the pale costa at the base fading to yellow toward the apex. There are figurues illustrating the differences on one page at Palaeosia sp.(2) page 2/2 on the disc supporting Part 2 of Moths in Victoria.
