Adaptive Introgression across Species Boundaries in Heliconius Butterflies
Figure 1
Geographic distribution and phenotype radiation of the species and races used in this study.
(a) H. melpomene (circles) and (b) H. cydno (triangles), H. timareta (squares) and H. heurippa (diamonds). Taxa with a rayed phenotype are coloured orange, red-banded phenotypes (red band in the forewing) are red and, those taxa lacking a dorsal red wing phenotype are yellow. The distributions of sampled taxa are estimated from locality data compiled by Neil Rosser.
