Cocoon

More than amazing - it's haunting and inspirational.
Very wasp-like isn't it? Is this one of the stinging ants?

For some reason, it reminds me of this.

I think they do sting. The simple addition of wings on males strongly recalls their relationship to wasps for me as well.

The sting must be a secondarily evolved structure, since it has been demonstrated that ants are derived from the Coleoptera. :)

@ Adrian:

Yes, the females of Cerapachys ants have well-developed stings.
But the males of even ants with vestigial stings can look quite waspy, such as this picture of a Formica male (from Alex Wild collection). This is a genus notorious for its substitution of spraying a jet of formic acid rather than stinging: http://www.alexanderwild.com/Ants/Natural-History/Male-Ants/9403446_ga7….

Damn you, and damn this site! It is only a matter of days now before I know I will convince myself that I need a macro lens more than, say, food...

And then, when I get it, I won't come close to the quality of your photos. I suppose I can console myself in my weight loss.
