Figure 6. Experimental design of the four male mate choice experiments.

Experimental design of the male choice experiments performed between the Morphos originating from Ecuadorian populations of M. helenor (eastern population: M. h. theodorus and western population: M. h. bristowi, experiments 1–3) and from French Guiana (M. h. helenor and M. a. achilles, experiment 4), along with the associated preferences and visual cues tested. Note that the same males were used for experiments 1, 2, and 3.
