Discovery of Papilio bianor Cramer, 1777 (Lepidoptera: Papilionidae) in the Central Ryukyus, Japan: inference of the dispersal pathway based on morphological and genetic analyses

Zootaxa, Journal Year: 2025, Volume and Issue: 5584(3), P. 339 - 352

Published: Feb. 9, 2025

More than 120 species of migrated butterflies have been recorded in the Ryukyu Islands, Japan. Biogeographically, it is important to investigate origins and characteristics these as they might establish populations after accidental migration. In August 2016, a Papilio (Achillides) butterfly was collected on Sesoko Island, approximately 600 m from Okinawa Main Island. Although ryukyuensis Fujioka native this area, individual had different wing markings species. To identify infer its origin, both morphological genetic analyses were conducted. Morphological analysis indicated that identification either bianor thrasymedes Fruhstorfer Taiwan or Cramer Mainland China. Subsequently, confirmed should be assigned P. b. thrasymedes. This suggests Taiwan, possibly influenced by Typhoon No. 10 2016.

Whole‐genome data shed light on speciation and within‐species differentiation of the Papilio machaon complex around the Mediterranean Basin

Systematic Entomology, Journal Year: 2025, Volume and Issue: unknown

Abstract Within swallowtail butterflies, the type species Papilio machaon Linnaeus has fostered many studies leading to a complex taxonomy. With >40 subspecies formally recognized in Palaearctic and recently simplified 14 subspecies, there is still need address taxonomic delineation within this complex. A previous phylogenomic analysis including Holarctic revealed that P. formed several monophyletic groups, treat saharae Oberthür as Nearctic separate ( bairdii Edwards).

A cryptic new species of tiger swallowtail (Lepidoptera, Papilionidae) from eastern North America

ZooKeys, Journal Year: 2025, Volume and Issue: 1228, P. 69 - 97

Published: Feb. 14, 2025

In the eastern Great Lakes region of North America, two tiger swallowtail species have previously been recognized, Papilioglaucus Linnaeus, 1758 and Papiliocanadensis Rothschild & Jordan, 1906. A third entity, Midsummer Tiger Swallowtail, has treated as a P.glaucus×canadensis hybrid, exhibits mosaic both intermediate unique morphological biological traits. Here we demonstrate that rather than being localized, historically recent hybrid phenomenon, Swallowtail maintains its physiological distinctness over large geographic in absence one or putative parental species, was first documented literature nearly 150 years ago. Papiliosolstitius sp. nov. is physiologically delaying post-diapause development, which results allochronic isolation between spring flights P.glaucus P.canadensis, late summer flight P.glaucus. Similarly, range spans northern terminus southern limits remaining distinct areas sympatry. Defining taxonomic identity this evolutionary lineage provides an important baseline for further inquiry into what served exemplary group study.

Reproductive Barriers and Genomic Hotspots of Adaptation During Allopatric Species Divergence

Molecular Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

ABSTRACT Theory predicts that in allopatric populations, genomic divergence and reproductive barriers may be driven by random genetic drift thereby evolve slowly large populations. However, local adaptation under selection also play important roles, which remain poorly characterised. Here, we address three key questions young species: (a) How widespread are signatures of adaptive divergence?, (b) What is the functional space along sister species show at level? (c) quickly might prezygotic postzygotic evolve? Analysis 82 re‐sequenced genomes Oriental Papilio polytes group revealed surprisingly hotspots intense selective sweeps hundreds genes, spanning all chromosomes, rather than only a few islands. These genes involved diverse ecologically functions such as wing development, colour patterning, courtship behaviour, mimicry, pheromone synthesis olfaction, host plant use digestion secondary metabolites, could contribute to subsequent isolation. Divergence appeared have evolved conjunction with consequences: behavioural hybridisation experiments strong assortative mate preference (prezygotic barriers) well timespans short 1.5 my, indicating speciation was already complete incipient. Our study thus demonstrates an underappreciated role potential creating genome‐wide rapid molecular evolution during differentiation species.

Acute and Long-Term Consequences of Co-opted doublesex on the Development of Mimetic Butterfly Color Patterns

Abstract Novel phenotypes are increasingly recognized to have evolved by co-option of conserved genes into new developmental contexts, yet the process which co-opted modify existing programs remains obscure.

Spectral variation and pigmentary basis of ornamental and mimetic wing colour patches of swallowtail butterflies

Evolutionary Journal of the Linnean Society, Journal Year: 2024, Volume and Issue: 3(1)

Published: Jan. 1, 2024

Abstract Colours and colour patterns are diverse traits that often used as visual signals. To test ecological evolutionary drivers of these signals, a clear understanding their nature variation is necessary. Here we characterize in wing coloration mormon swallowtail butterflies (Papilio, subgenus Menelaides). These species exhibit two kinds patches on black wings: creamy white/yellow/green presumably sexual ornaments, pure white mimetic Using reflectance spectrophotometry quantified spectral properties background between sexes, surfaces, mimicry status. We found brightness saturation the were less variable across mimetic/nonmimetic However, contrast higher dorsal surfaces than ventral was males females. Colour nonmimetic brighter more saturated whole spectrum compared to butterflies. Thus, our study characterizes an extraordinary signal radiation wings butterflies, model clade ecology, evolution, genetics. Our results generate numerous hypotheses about functions patches, which may guide further behavioural experiments. Finally, using liquid chromatography-mass spectrometry identified pigment papiliochrome-II be chemical basis presumed ornaments swallowtails.

Biogeographic–tectonic calibration of 14 nodes in a butterfly timetree

Cladistics, Journal Year: 2023, Volume and Issue: 39(4), P. 293 - 336

Published: June 6, 2023

Abstract The butterfly subtribe Coenonymphina (Nymphalidae: Satyrinae) comprises four main clades found, respectively, in (1) the Solomon Islands, (2) Australasia, (3) NW South America and (4) Laurasia, with a phylogeny: 1 (2 (3 + 4)). In assessing biogeographic evolution group we rejected conversion of fossil‐calibrated clade ages to likely maximum by imposition arbitrary priors. Instead, used biogeographic–tectonic calibration, accepted as minima. Previous studies have this approach date single nodes (phylogenetic–biogeographic breaks) group, but extended methodology multiple nodes. Within whole, 14 coincide spatially ten major tectonic events. addition, phylogenetic sequence these conforms chronological events, consistent vicariance origin clades.
