We observed the foraging behavior in 8 colonies of Syntermes molestus (Burmeister) in the Gran Sabana, Bolívar State, Venezuela. We determined the organization of foraging behavior. This behavior is nocturnal, starting approximately at 20:00 hours and ending around 2:00. The soldiers are the first to leave the nest, positioning themselves in the periphery of the foraging outlets. These outlets can be a few meters from the main nest and the number of soldiers present varies from 6 to 10. Consequently, workers join in with a forward and backward displacement until a foraging column is formed. The columns are composed of both castes (soldiers and workers), sheltered in the periphery by files of soldiers. The outlet holes are rebuilt daily, and at the end of foraging the workers seal the outlet using soil mixed with saliva with the help of their mouth appendices.
