Sex	Category	mv±sd	max	min	n	ns
Female	Pollen	0.1155±0.0158	0.1426	0.0953	6	55
Female	Glass-beads	0.0573±0.0175	0.0757	0.0260	7	71
Male	Pollen	0.0928±0.0228	0.1374	0.0584	10	83

Mean extinction values (mv), standard deviations (sd), maxima (max), minima (min), number of sampled individuals (n), and total number of saliva samples (ns) from two categories for female and male Heliconius melpomene. The total number of saliva samples represents the pooled samples resulting in one data-point per individual for the analysis. The category “pollen” means that the saliva samples were collected with the aid of either fresh or frozen pumpkin pollen (for analysis both were combined); “glass-beads” refer to saliva samples collected by means of glass-beads.
