Ants Behave like Light across Lenses

Caption

Figure 1. Similarities between dispersion of light and dispersion of ant trails across convex and concave lenses between light sources and target, or nest and food patch. Light rays that originate from the light source and pass through a lens (a) to reach the target can travel through the wider area of the convex lens (b) compared to the concave lens (c). Ants (d) travelling between their nest and food source behave in a generally similar manner: they disperse more across the convex (e) than that across the concave "lens" (f) made of Velcro that slows ants down. The underlying hypothetical reason for this similarity is the tendency to reduce travel time by the both, the light and the ants.
