Old Termites Turn Into Self-Destructing Chemical Weapons

Question: what's the best line of defense when you're old and crotchety and your body's not working quite like it used to? The answer, of course, is to turn yourself blue and explode when provoked. At least if you're a termite.

Worker termites' mouths will wear down from years (but really more like a year or two, tops) of hard labor. As they age, they start to build up blue rings on their backs, the blue color because of a copper-binding protein. The stuff builds up under the cuticle over their lifetime, growing more and more poisonous as they age. And when they're in the twilight of their lives, what do they do if a rival termite approaches, ready to tussle? Rather than throw 'bows, er, mandibles that just don't work like they used to, the termite blows up, coating its enemy in a toxic goop. Imagine if your grandpa did that next time you told him it's no longer safe for him to get behind the wheels of his Cadillac.

So while human logic suggests that youngins are more volatile and hot-headed, when it comes to this brand of insect, that maxim doesn't prove true. [ScienceMag via Ars Technica via Geekosystem]

This is the closest thing to video of this that I've been able to find. Don't actually see the explosion in this one, just an expanding bubble on it's back. Anyone find anything better?
