- We describe an emigration of the Neotropical army ant Eciton mexicanum where the head of the emigration column was separated in time from previous raid column activity, and the emigration was not connected to the new bivouac site by a column of workers. Over 12 h elapsed between raid activity and the onset of emigration, suggesting the emigration followed a long-lasting pheromone trail. We suggest the bivouac site had been selected the night before the emigration by foraging workers.
