Superloud Moth Jams Bat Sonar

Another example in which, interestingly, the prey goes silent instead: http://www.sciencedaily.com/releases/2006/09/060923105230.ht...

This is a really interesting counter-adaptation. I wonder what the mechanism might be. Does it prevent echolocation or is it eliciting a pain response?

It would also be interesting to see the counter-adaptation in the bats to this counter-adaptation in the moth. The approach which first comes to mind is passive sonar.

I love evolution.
