[Is that ant saying "hi"...?]
When I took this picture I didn't know I would get this much detail. It was hard to focus as the little ant was moving very quickly. But when I saw this picture on my monitor I felt like the ant was shouting then. May be in an inaudible way. But don't know why I feel like that the ant was shouting to his neighbouring ants saying: "Hey buddies... I'm about to fly now!!" A weird guess but look closely at the picture... I think you won't fully disagree.
