I went to a small run-off stream. That morning I saw three Stencilled Hairstreak Butterflies interacting around an acacia. There was initially one, then a second one joined in, then a third. Sometimes one would sit out on a nearby acacia branch but they would be back in the swirling flying milieu shortly afterwards. There were some other small groups doing the same thing further along. I am unsure if this was breeding behaviour, as I cannot differentiate the sexes with these photographs but I enjoyed the flying display.
