on my way back to the car it was just luck that I looked this way and saw the butterflies (even though I saw the shells last year). There were two lots on two different sapling wattles. Some were flying free. But most were still round the ants. They moved like one - at one stage, all moving away from me round the otherside. It was great to see. Haven't seen this since Pambula Beach about 4 or 5 years ago!
