A Butterfly!

This is the very first butterfly I have ever tried to capture.  I am pleased enough because it is a windy day and I have to confess to my camera being hand held.  I thought I was having a bit of a Blip break for various reasons, but went out for a walk just to check out the garden.  Being Tiny Tuesday, I just had to put this up here.  I know nothing about butterfly names, but on investigation I wonder if this could be a female Pontia  protodice, although it was on the native flowers, not exotics and I can't find an indication that it is found in Australia. So really, I have no idea!
