Further up the northern side of Violet Hill, I came across two big butterflies which were more or less keeping as still as that changeable lizard because they were in the middle of a certain act that seems to require members of their species to not flit and flutter about the way they otherwise tend to do! And while I have caught more than one pair of butterflies (and, for that matter, moths too) going at it previously, I have to say that this particular pair of Papilionidae were the largest butterflies I've seen performing this particular act.
