This ant looks like it’s wearing the insect equivalent of tuxedo shorts. Formal wear and pasty white legs.
If you visit Cape Tribulation, keep an eye out for these little insects. Only 2-3 millimeters long, they are one of the most common ants in that area. I found them nesting in nearly every rotting log I looked at. Insects don’t have to be rare to be beautiful!
Incidentally, Australian ant expert Steve Shattuck has photos of a major worker here: http://www.flickr.com/photos/steve_shattuck/3822017590/
