What was it? I searched through my butterfly references in vain, looking for a black and white butterfly with orange tufts on its legs and abdomen. Then the penny finally dropped. I looked in the moth references instead and there it was. The Grapevine Moth Phalaenoides glycinae was flying around and feeding on the blossom of a Melaleuca.
Apparently it's a common day-flying moth but I don't remember seeing one before. There aren't any grapevines within cooee either but as it also breeds on guinea-flowers and willow herbs and both of those plants are in the bush nearby I'm supposing it was 'at home'.
The moth was moving fairly quickly around the blossom and the first photo is blurred but I'm including it because it shows the remarkable orange tufts. Now why would a moth want to evolve that colouring?
And on one of my bush rambles (on a day that wasn't enervatingly hot) this butterfly sat still on a bracken frond long enough for me to grab a couple of photos. It's a female Common Brown. The larva feed on Tussock Grass and Kangaroo Grass.
