I ride my bike down to Tooan Tooan Creek in Hervey Bay, Qld and in amongst the mangrove swamp I’m captivated by four different types of butterflies flitting about in the sunlight.  To onlookers I must have looked like some sort of mad woman dashing back and forth about the swamp wearing a bike helmet and waving a Nikon. On the north side of the swamp the flying fox colony is chattering and screeching in the trees, so before long the whole dashing performance thing is repeated.
