- Figure 1. Comparison of External Eye Anatomy and Hunting Strategies of Dragonflies and Damselflies (A) Frontal and lateral views of a dragonfly with holoptic eyes (Sympetrum vulgatum) and a demoiselle damselfly with dichoptic eyes (Calopteryx splendens). Yellow lines indicate visual area sampled by the dorsal (~60Ǫ elevated in dragonflies) [10] and frontal foveae, respectively. (B) Predatory flights of a dragonfly (i, Erythemis simplicicollis; Figure S1B; Video S1) and demoiselle (ii, Calopteryx aequabilis; Figure S1C; Video S2) while chasing an artificial prey (blue) reconstructed in 3D. Predator head positions are represented as a continuous red curve, with the body axis plotted at 10-ms intervals to indicate orientation of the predator throughout the attack (red lines). Line of sight between predator head position and artificial prey in gray. (C) Spherical plots, tracing the average subtended position of the prey (blue) compared to the body axis of the predator throughout the flight (red). Cones depict the 95% confidence interval (CI) of the prey just before the predator's first movement. In dragonfly attacks, the prey (dark blue) was on average aligned above the dragonfly body axis by 32.6Ǫ just prior to the first movement of the predator (95% CI = ±12.4Ǫ; n = 8) and by 33.7Ǫ throughout flight (95% CI = ±5.3Ǫ; n = 8). In demoiselle attacks, the prey (light blue) was on average aligned above the body axis by 13.9Ǫ just prior to the first movement of the predator (95% CI = ±13.0Ǫ; n = 10) and by 11.4Ǫ throughout flight (95% CI = ±6.5Ǫ; n = 10).
