To I biologists, however, bright coloration has been a con- stantly renewed puzzle because it makes an insect a highly FIGURE 1 Pseudosphinx tetrio hawk moth caterpillar from the Peruvian conspicuous prey to prospective predators.

It is certainly contextually defined, because the hawk moth caterpillars (Fig. 1). In a reply to Darwin about propensity of an animal to eat something is highly dependent this puzzle, Alfred R.

Alfred Russel Wallace and the Darwinian Species Concept
Gayana 73(2): Suplemento, 2009 ISSN 0717-652X ALFRED RUSSEL WALLACE AND THE Darwinian SPECIES CONCEPT: HIS paper ON THE swallowtail BUTTERFLIES (PAPILIONIDAE) OF 1865 ALFRED RUSSEL WALLACE Y EL concepto darwiniano DE ESPECIE: SU TRABAJO DE 1865 SOBRE MARIPOSAS papilio (PAPILIONIDAE) Jam ES MA LLET 1 Galton Laboratory, Department of Biology, University College London, 4 Stephenson Way, London UK, NW1 2HE E-mail: [email protected] Abstract Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most significant papers. The paper used butterflies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the description of some 20 new species. Wallace argued that the Papilionidae were the most advanced butterflies, against some of his colleagues such as Bates and Trimen who had claimed that the Nymphalidae were more advanced because of their possession of vestigial forelegs. In a very important section, Wallace laid out what is perhaps the clearest Darwinist definition of the differences between species, geographic subspecies, and local ‘varieties.’ He also discussed the relationship of these taxonomic categories to what is now termed ‘reproductive isolation.’ While accepting reproductive isolation as a cause of species, he rejected it as a definition. Instead, species were recognized as forms that overlap spatially and lack intermediates. However, this morphological distinctness argument breaks down for discrete polymorphisms, and Wallace clearly emphasised the conspecificity of non-mimetic males and female Batesian mimetic morphs in Papilio polytes, and also in P. -

Such zones have been regarded as strong evidence for allopatric divergence by proponents of the Pleistocene forest refugia theory, a vicariance hypothesis frequently used to explain diversification in the Amazon basin. A central prediction of the refugia and other vicariance theories is that the taxa should have a common history so that divergence times should be coincident among taxa. A suture zone for Ithomiinae butterflies near Tarapoto, NE Peru, was therefore studied to examine divergence times of taxa in contact across the zone. We sequenced 1619 bp of the mitochondrial COI/COII region in 172 individuals of 31 species from across the suture zone. Inferred divergence times differed remarkably, with divergence between some pairs of widespread species (each of which may have two or more subspecies interacting in the zone, as in the genus Melinaea) being considerably less than that between hybridizing subspecies in other genera (for instance in Oleria). -

The Speciation History of Heliconius: Inferences from Multilocus DNA Sequence Data
The speciation history of Heliconius: inferences from multilocus DNA sequence data by Margarita Sofia Beltrán A thesis submitted for the degree of Doctor of Philosophy of the University of London September 2004 Department of Biology University College London 1 Abstract Heliconius butterflies, which contain many intermediate stages between local varieties, geographic races, and sympatric species, provide an excellent biological model to study evolution at the species boundary. Heliconius butterflies are warningly coloured and mimetic, and it has been shown that these traits can act as a form of reproductive isolation. I present a species-level phylogeny for this group based on 3834bp of mtDNA (COI, COII, 16S) and nuclear loci (Ef1α, dpp, ap, wg). Using these data I test the geographic mode of speciation in Heliconius and whether mimicry could drive speciation. I found little evidence for allopatric speciation. There are frequent shifts in colour pattern within and between sister species which have a positive and significant correlation with species diversity; this suggests that speciation is facilitated by the evolution of novel mimetic patterns. My data is also consistent with the idea that two major innovations in Heliconius, adult pollen feeding and pupal-mating, each evolved only once. By comparing gene genealogies from mtDNA and introns from nuclear Tpi and Mpi genes, I investigate recent speciation in two sister species pairs, H. erato/H. himera and H. melpomene/H. cydno. There is highly significant discordance between genealogies of the three loci, which suggests recent speciation with ongoing gene flow. Finally, I explore the phylogenetic relationships between races of H. melpomene using an AFLP band tightly linked to the Yb colour pattern locus (which determines the yellow bar in the hindwing). -

Polymorphism in aposematic animals and coexistence of multiple mimicry rings within a habitat are not predicted by classical MuÈ llerian mimicry. The butter¯y Heliconius numata Cramer (Lepidoptera: Nymphalidae; Heliconiinae) is both polymorphic and aposematic. The polymor- phism is due to variation at a single locus (or `supergene') which determines colour patterns involved in MuÈ llerian mimicry. We sampled 11 sites in a small area (approx. 60 ´ 30 km) of North- eastern Peru for H. numata and its co-mimics in the genus Melinaea and Athyrtis (Ithomiinae), and examined the role of temporal and spatial heterogeneity in the maintenance of polymorphism. Colour-patterns of Melinaea communities, which constitute the likely `mimetic environment' for H. numata, are dierentiated on a more local scale than morphs of H. numata, but the latter do show a strong and signi®cant response to local selection for colour-pattern. -

Nymphalidae: Ithomiinae)
STUDIES ON THE ECOLOGY AND EVOLUTION OF NEOTROPICAL ITHOMIINE BUTTERFLIES (NYMPHALIDAE: ITHOMIINAE) by GEORGE WILLIAM BECCALONI A thesis submitted for the degree of Doctor ofPhilosophy ofthe University ofLondon October 1995 Biogeography and Conservation Laboratory Centre for Population Biology Department of Entomology Imperial College The Natural History Museum Silwood Park Cromwell Road Ascot London SW7 5BD Berkshire SL5 7PY 2 To my mother, Benjie & Judy in love and gratitude 3 ABSTRACT Two aspects ofthe ecology ofNeotropical ithomiine butterflies (Nymphalidae: Ithomiinae) are discussed: mimicry (Chapters 2, 3) and species richness (Chapters 4, 5). Chapter 2 defines eight mimicry complexes involving ithomiines and other insects found in eastern Ecuador. These complexes are dominated by ithomiine individuals. Hypotheses to explain polymorphism in Batesian and Mullerian mimics are assessed. In Chapter 3, evidence that sympatric ithomiine-dominated mimicry complexes are segregated by microhabitat is reviewed. Data confirm that sympatric complexes are segregated vertically by flight height. Flight height is shown to be positively correlated with larval host-plant height. Host-plant partitioning between species in a butterfly community results in the formation of microhabitat guilds of species, and evidence suggests that mimicry may evolve between species which share a guild, but not between guilds. Models for the evolution of mimicry complexes in sympatry, and for polymorphism and dual sex-limited mimicry in Mullerian mimics, are discussed in the light of these findings. Chapter 4 investigates relationships between species richness offamilies and subfamilies ofNeotropical butterflies and overall butterfly species richness at local and regional scales. A strong positive correlation is demonstrated between ithomiine richness and the species richness of all other butterflies. -
Ecological Divergence and Speciation in Heliconius Cydno and H
Ecological divergence and speciation in Heliconius cydno and H. melpomene by Russell Edward Naisbit A thesis submitted for the degree of Doctor of Philosophy of the University of London September 2001 Department of Biology University College London To my family, for their support and encouragement throughout this crazy endeavour 2 “It is hardly an exaggeration to say, that whilst reading and reflecting on the various facts given in this Memoir, we feel to be as near witnesses, as we can ever hope to be, of the creation of a new species on this earth.” Charles Darwin, Natural History Review: Quarterly Journal of Biological Science, 1863. From a review of “Contributions to an Insect Fauna of the Amazon Valley,” in which Henry Walter Bates gave an adaptive explanation for mimicry in Amazonian butterflies and argued that variation in mimicry might cause speciation 3 Abstract We are in the midst of a renaissance in speciation research. There is a return to Darwin’s belief in the role of natural selection in driving speciation, after a lengthy focus on geographic isolation and hybrid sterility. Here I describe the ecological, behavioural, and genetic bases of speciation in Heliconius cydno and Heliconius melpomene (Lepidoptera: Nymphalidae). The two species are sympatric in tropical rainforest across most of Central America and the foothills of the Andes. Ecological differentiation allows coexistence of these sister species despite rare hybridisation. Divergence in microhabitat and larval host plant use has reduced both the potential for gene flow and for competition. In Panama H. cydno uses most Passiflora species in closed canopy forest, whilst H.
