Blue Mountains Moth

If you happened to be in a certain Blue Mountains village this morning and you happened to notice a woman crawling around on her hands and knees in the street, chasing something, well, it was me.

And this is what I was chasing.

Naturally enough I've never seen this moth before, and I don't have time to try and make an ID.  

Pretty, innit!

Edit:  Have done a bit more research since I got home, and it is - to the best of my knowledge - a sun moth.  It's a very small family of moths, often mistaken for butterflies.

Castniidae, or castniid moths, is a small family of moths with fewer than 200 species: The majority are Neotropical with some in Australia and a few in south-east Asia. These are medium-sized to very large moths, usually with drab, cryptically-marked forewings and brightly coloured hindwings. They have clubbed antennae and are day-flying, and are often mistaken for butterflies. Indeed some previous classification systems placed this family within the butterflies or skippers. The Neotropical species are commonly known as giant butterfly-moths, the Australian and Asian species as sun moths. The larvae are internal feeders, often on roots of epiphytes or onmonocotyledons (Edwards et al., 1999: 184-188).
