Perceptual differences in trail-following leaf-cutting ants relate to body size by Kleineidam, C.J., Rössler, W., Hölldobler, B., Roces, F.

“…Leaf-cutting ants of the genus Atta have highly size-polymorphic workers, and size is related to division of labor. We studied trail-following behavior of…”
