@futurebird I have seen plenty of bull-ants, and have the usual aversion of someone who has been stung by a couple. I encounter them regularly on walking tracks and make a point of giving them a wide birth (those things make belligerent eye contact, as if to say 'you think you're tough? Do you? Huh? Do you?')
I've never seen one stumbling back at dawn.
But then, I'm seldom awake that early.
