Melanism in Lepidoptera, either industrial or in mimicry, is one of the most commonly cited examples of natural selection [1] [2]. Despite extensive studies of the frequency and maintenance of melanic genes in insect populations [1] [2], there has been little work on the underlying molecular mechanisms. Nowhere is butterfly melanism more striking than in the Eastern Tiger Swallowtail (Papilio glaucus) of North America [3] [4] [5]. In this species, females can be either yellow (wild type) or… Expand
The peppered moth and industrial melanism: evolution of a natural selection case study
TLDR
Modelling and monitoring of declining melanic frequencies since the 1970s indicate either that migration rates are much higher than existing direct estimates suggested or else, or in addition, non-visual selection has a role. Expand
Insect melanism: the molecules matter
TLDR
Recent studies of the developmental genetics of melanin pigmentation in Drosophila, and of the genetics of pigmentation differences among other insect species, have provided valuable insights into the underpinnings of this important source of polymorphism throughout the Insecta. Expand
The Role of the Dopamine Melanin Pathway in the Ontogeny of Elytral Melanization in Harmonia axyridis
TLDR
It is demonstrated for the first time that dopamine-derived melanin is the main contributor in elytra melanization in H. axyridis, bringing novel insights into melanin production in holometabolous insects. Expand
Industrial Melanism in the Peppered Moth Is Not Associated with Genetic Variation in Canonical Melanisation Gene Candidates
TLDR
This study demonstrates that the ‘carbonaria gene’ is not a structural variant of a canonical melanisation pathway gene, neither is it a cis-regulatory element of these enzyme-coding genes. Expand
Melanin-synthesis enzymes coregulate stage-specific larval cuticular markings in the swallowtail butterfly, Papilio xuthus
TLDR
Specific larval cuticular color patterns are regulated by stage-specific colocalization of enzymes in epidermal cells rather than by the differential uptake of melanin precursors into individual epider mal cells. Expand
A Pathway Analysis of Melanin Patterning in a Hemimetabolous Insect
TLDR
It is suggested that melanin genes are used in two distinct ways: a “painting” mode, using predominantly melanin-promoting factors in areas that generally lack black coloration, and, alternatively, an “erasing” modes, using mainly melanin -suppressing factors in regions where black is the dominant pigment.

Pheomelanin in the secondary sexual characters of male parasitoid wasps (Hymenoptera: Pteromalidae).
TLDR
A convergent evolution of melanin-based male sexual ornaments between vertebrates and wasps can be suggested, opening to a new line of comparative evolutionary studies. Expand
Functional conservation and diversification of yellow-y in lepidopteran insects.
TLDR
This study conducted CRISPR/Cas9-mediated targeted mutagenesis of yellow-y in the tobacco cutworm Spodoptera litura and found that almost none of theyellow-y mutant embryos hatched unaided, providing evidence that S. lituraYellow-y has a novel important function in egg hatching, in addition to pigmentation.

  • 2009
TLDR
A graphical model is presented that connects various mimicry types by hypothetical character state changes within a phylogenetic framework and is useful to test novel hypotheses regarding the diversity and evolutionary directionality of Batesian mimicry in other systems. Expand
Convergent, modular expression of ebony and tan in the mimetic wing patterns of Heliconius butterflies
TLDR
A modular system in which particular combinations of genes are switched on whenever red, yellow or black pattern elements are favoured by natural selection for diverse and mimetic wing patterns is suggested. Expand

GENETICS OF MIMICRY IN THE TIGER SWALLOWTAIL BUTTERFLIES, PAPILIO GLAUCUS AND P. CANADENSIS (LEPIDOPTERA: PAPILIONIDAE)
TLDR
Results from more than 12 yr of rearing tiger swallowtails, including interspecies hybrids, indicate that the absence of mimetic P. canadensis females is due to both a high frequency of the “suppressing” allele scan and low frequency ofThe black‐pigment‐determining b + allele in P. glaucus populations outside the hybrid zone is low.

Regulation of dopa decarboxylase expression during colour pattern formation in wild-type and melanic tiger swallowtail butterflies.
TLDR
The regulation of enzyme synthesis observed in the yellow/black pattern of a single wing, is similar to that involved in melanism and it is inferred that dopa decarboxylase activity must be regulated in concert with downstream enzymes of either the melanin and/or the papiliochrome specific pathways, forming part of a developmental switch between yellow or black.

Insect pigmentation: activities of beta-alanyldopamine synthase in wing color patterns of wild-type and melanic mutant swallowtail butterfly Papilio glaucus.
TLDR
It is clear, that papiliochrome synthesis in yellow scales is switched on by BAS shifting dopamine into the papiliochromes pathway and out of the melanin pathway or vice versa. Expand
Abnormalities of wing pattern in the Eastern Tiger Swallowtail butterfly, Papilio glaucus
Abstract In much of its range Papilio glaucus L. has two forms of female, black and yellow, and the gene controlling the colour pattern is on the Y chromosome. Thus black mothers produce only blackExpand
Drosophila wing melanin patterns form by vein-dependent elaboration of enzymatic prepatterns
TLDR
It is discovered that in D. melanogaster and three other Drosophila species these wing melanin patterns are dependent upon and shaped by the circulation patterns of hemolymph in the wing veins, which can change during evolution to produce color pattern diversity. Expand

Conservation of a multidomain protein structure known from peptide synthetases should have functional implications on the putative reaction mechanism of peptide bond formation. Expand
