      Attack of legionary ants (also known as army ants or marabunta) to a wasp honeycomb. Impressive the level of swarm intelligence and collective computation to form that bridge.pic.twitter.com/StvDkmv8x8

      When this type of attack happens, the wasps usually escape and the ants do not leave until they've completely looted the honeycomb, carrying pupae, larvae, and eggs, as well as some adults who did not manage to escape They can even build across the water!pic.twitter.com/cuQxQbCor0

      At first I was thinking that this was merely a failure mode that happened when they decided to follow & build the bridge (premature optimization gone wrong). Or that there was something in the ceiling affecting the trail pheromones.

      But then a biologist pointed out something more fundamental. Many species ants have a hard time walking upside down. For ants it is more effective to follow the trail over a bridge that goes down and then up than in an inverted upside down walk. http://earthsky.org/earth/how-do-ants-walk-upside-down …

      Also likely that, upside down, the ants can't carry significant loads.

          Very good point! After all one of their main goals is to loot the precious items in the honeycomb.

          How do they start? Do they dangle down then swing up to the nest? Or do some of them manage to cling on to the underside of the roof across to the nest?
