 "Eciton burchellii" colonies have been found to inhabit areas with no direct sunlight, regulate their bivouac's temperature and airflow, and prefer the closed-canopy forest environment over a fragmented one.Temperature has been found to be the largest contributing factor to whether or not a swarm will cross into the open from a forest edge.When the ants meet an excessively hot patch, they will accelerate their movement, "shuttling" to minimize their exposure to the heat.
