Fig. 2 in Light affects the homing ability of Solenopsis invicta (Hymenoptera: Formicidae) foraging workers

Fig. 2. The importance of a fixed light source to foraging red imported fire ants, Solenopsis invicta. Time-to-trail-formation was recorded with a light source that changed sequentially to 1 of 4 symmetrically placed light sources or a single light source that was moved in a circle planar to the colony tray in 90° increments at 1 rpm. Bars represent mean time-to-trail-formation + standard error, ***P <0.0001. By inference, the mean time-to-trail-formation for the single light rotation was longer than the fixed light control.
