    The caterpillar relies on only a single species of ant – the ‘Myrmica’ ant.

    Ah, too bad. I was going to see if I could get ahold of some of these caterpillars for the garden. But we have the ubiquitous Argentinian Supercolony, so we’re out of luck.

    You’d think the ants would catch on after a while. Presumably the benefits outweigh the costs.

    If only they could be bred or GM to live only on fire ants. But I hear they’ve begun releasing a specialized wasp for them already.

    yeah, so much for swarm intelligence!

    As with similar parasitic relationships there will be a delicate balance between those two species, i.e. there will be far more ant colonies than preying caterpillars.

    It’s similar with cleaner fishes and sabre-toothed blennies ( http://en.wikipedia.org/wiki/Sabre-toothed_blenny ). The latter look like cleaner fishes, but are in fact taking bites of healthy tissue from the larger fishes expecting to be cleaned.

    This also only works when there are far more real cleaner fishes than fake ones.

    David Attenborough DID do a segment on this caterpillar! I can’t remember which series… Life in the Undergrowth, I think.

    The remarkable thing here is not the caterpillars, but the wasps. I’m surprised that Baker didn’t check out the video in the source. It is narrated by Attenborough.

    @spike55151: I had forgotten about that Attenborough footage, but it’s so cool I added it to the original article. Thanks for the tip!
