Mega Ants

To give a little sense of scale here, the branch that these guys were were climbing down was probably an inch in diameter.   So this was on an island in the Whitsundays, hiking from one side to another to get to the much anticipated white silica sandy beaches.  The monochrome way this photo turned out was pretty cool, and the green, almost transparent bodies of the ants could just disappear in camouflage.
