I'm not really a good insect photographer, it really isn't my forte but when I happened upon this caterpillar I just had to shoot him. If anyone can identify this and the related butterfly I would be most interested.
Might I add, none of the markings or attributes (it would seem) are friendly. When it senses movement down either side of it's body, it turns those four golden tufts in that direction. Stroke it's back and it inverts what I can only refer to as "tail feathers". I have a nasty suspicion that although decorative that you would come away with at least an itch if you came into contact with it. Still, nothing a small poking device didn't overcome...
Update: It also has another curious name, that of "rusty tussock moth" which I find amusing. Here are details concerning the creature:
"The larvae are easily recognized by their horn-like tufts of hair-like setae. There are 4 toothbrush-like tufts along the back, and hair pencils that project from the sides at the front and at the back. The body is black, and there are red tubercules along the sides and back. They have defensive glands at the back, and wipe their setae against them to charge them with toxins (Wagner 2005) They grow to about 30 mm."
