Thanks for sharing. Fascinating stuff. Anyone know if this documentary is available on dvd (region 2: UK) ?
I bought my copy from here a few years ago ( http://www.science-shop.de/artikel/842575 ) . Fascinating movie, highly recommendable if your not an expert on ants but just interested :-)
Thanks for the info, Nicolas.
