FIGURE 13 in Alternative facts: a reconsideration of putatively natural interspecific hybrid specimens in the genus Heliconius (Lepidoptera: Nymphalidae)
FIGURE 13. Hybrid #11 (dorsal; ventral). Peru: Loreto, Río Itaya [near Iquitos]. 1997. Interpreted by Mallet et al. (2007) to be an F1 hybrid of H. numata aurora (Fig. 11) and H. melpomene malleti (Fig. 14), based on wing shape and the FW yellow band. This specimen, apparently collected near Iquitos, Peru by an unnamed third party is in the Neukirchen collection, purchased by the University of Florida's McGuire Center for Lepidoptera and Biodiversity Research (FLMNH). The white marginal dots, the absence of red basal dots, and the v-shaped distal ends of the red rays on the VHW all suggest that a more likely cross would be H. numata x H. elevatus (e. g., H. elevatus pseudocupidineus, Fig. 3). While still interspecific, such a hybrid would be between very closely-related species, rather than more distantlyrelated members of separate clades.
Data from: Divergence with gene flow across a speciation continuum of Heliconius butterflies
Background: A key to understanding the origins of species is determining the evolutionary processes that drive the patterns of genomic divergence during speciation. New genomic technologies enable the study of high-resolution genomic patterns of divergence across natural speciation continua, where taxa pairs with different levels of reproductive isolation can be used as proxies for different stages of speciation. Empirical studies of these speciation continua can provide valuable insights into how genomes diverge during speciation. Methods: We examine variation across a handful of genomic regions in parapatric and allopatric populations of Heliconius butterflies with varying levels of reproductive isolation. Genome sequences were mapped to 2.2-Mb of the H. erato genome, including 1-Mb across the red color pattern locus and multiple regions unlinked to color pattern variation. Results: Phylogenetic analyses reveal a speciation continuum of pairs of hybridizing races and incipient species in the Heliconius erato clade. Comparisons of hybridizing pairs of divergently colored races and incipient species reveal that genomic divergence increases with ecological and reproductive isolation, not only across the locus responsible for adaptive variation in red wing coloration, but also at genomic regions unlinked to color pattern. Discussion: We observe high levels of divergence between the incipient species H. erato and H. himera, suggesting that divergence may accumulate early in the speciation process. Comparisons of genomic divergence between the incipient species and allopatric races suggest that limited gene flow cannot account for the observed high levels of divergence between the incipient species. Conclusions: Our results provide a reconstruction of the speciation continuum across the H. erato clade and provide insights into the processes that drive genomic divergence during speciation, establishing the H. erato clade as a powerful framework for the study of speciation.
Figure 2 in Oviposition preference and larval performance in a Heliconius erato phyllis (Lepidoptera: Nymphalidae) population from southeastern Brazil: is there a positive relationship?
Figure 2. Influence of larval host plant species on (A) Head capsule width (fourth instar larvae); (B) larval development time; (C) forewing length; (D) survival (proportion of individuals that reached the adult stage) of Heliconius erato phyllis reared in the laboratory under controlled conditions. Data are presented as median ± interquartiles (A, B), mean ± standard error (C) and percentages (D). For each trait, different letters above bars indicate significant differences among host plants (Dunn's multiple comparison tests for A and B, and Tukey's multiple comparison tests for C).
