> Actually ... that sounds interesting ... can you post a link to the > article about synchronizing fireflies? It's from CMJ, but not the one you'd think -- College Mathematics Journal, vol 37 no 3 May 2006, "Fireflies flashing in unison" by Ying Zhou, Walter Gall, and Karen Nabb. The "references" include numerous other articles on the phenomenon, but I don't see any web link.
