Butterfly was flying from flower to flower on the one plant, hovering with wings flapping rapidly while feeding, then moving on to the next plant. Flowers didn't appear to trigger. A few butterflies were seen doing this. Host plant here will be Tasmannia xerophila which is plentiful.
One butterfly exhibiting aggressive, territorial behaviour towards other butterflies. Flying between three large flowering Senecio linearifolius linearifolius plants, shooing off all who came near. It never landed and I couldn't get a photo with my phone.
