Genomics, Population Divergence, and Historical Demography of the World's Largest and Endangered Butterfly, The Queen Alexandra's Birdwing

Genome Biology and Evolution, 2023
AbstractThe world's largest butterfly is the microendemic Papua New Guinean Ornithoptera alexandrae. Despite years of conservation efforts to protect its habitat and breed this up-to-28-cm butterfly, this species still figures as endangered in the IUCN Red List and is only known from two allopatric populations occupying a total of only ∼140 km².

Queen Ants Make Distinctive Sounds That Are Mimicked by a Butterfly Social Parasite

Science, 2009
Ants dominate terrestrial ecosystems through living in complex societies whose organization is maintained via sophisticated communication systems. The role of acoustics in information exchange may be underestimated. We show that Myrmica schencki queens generate distinctive sounds that elicit ...

Mimicry in viceroy butterflies is dependent on abundance of the model queen butterfly. [PDF]

Commun Biol, 2019
AbstractMimics should not exist without their models, yet often they do. In the system involving queen and viceroy butterflies, the viceroy is both mimic and co-model depending on the local abundance of the model, the queen. Here, we integrate population surveys, chemical analyses, and predator behavior assays to demonstrate how mimics may persist in ...

The Queen Butterfly, Danaus Chrysippus (L.) (Lepidoptera: Nymphalidae) at Khartoum, Sudan. [PDF]

Egyptian Academic Journal of Biological Sciences. A, Entomology, 2012
Dans la région de l'Afrique orientale et centrale, le papillon aposématique D. chrysippus se caractérise par une écologie inhabituelle, en raison de la co-occurrence du polymorphisme, du mimétisme et de la distorsion du sex-ratio. Dans cet article, nous décrivons une étude menée pour D. chrysippus à Khartoum, basée sur des investigations morphologiques

Survival of eggs to third instar of late-summer and fall-breeding monarch butterflies (Danaus plexippus) and queen butterflies (Danaus gilippus) in north Texas

Journal of Insect Conservation, 2022
Abstract Introduction Eastern migratory monarch butterflies (Danaus plexippus) have declined over 80% in recent years, but little is known about fall reproduction in the southern U.S. where monarchs may compete with queen butterflies (Danaus gilippus).

On Linnaeus’ (1764) butterfly type materials missing from the Museum of Evolution of Uppsala University (Section of Zoology) and the case of Papilio hermione [PDF]

Nota Lepidopterologica
We briefly analyse the history of Queen Ulrika’s and of Linnaeus’ butterfly collections. We show that the type materials of some species were likely moved from Queen Ulrika’s to Linnaeus’ collection before 1803. We provide evidence that Honey and Scoble (

Whole-chromosome hitchhiking driven by a male-killing endosymbiont.

PLoS Biology, 2020
Neo-sex chromosomes are found in many taxa, but the forces driving their emergence and spread are poorly understood. The female-specific neo-W chromosome of the African monarch (or queen) butterfly Danaus chrysippus presents an intriguing case study ...

Impact of duplicate gene copies on phylogenetic analysis and divergence time estimates in butterflies

BMC Evolutionary Biology, 2009
Background The increase in availability of genomic sequences for a wide range of organisms has revealed gene duplication to be a relatively common event.

Testing the role of the Red Queen and Court Jester as drivers of the macroevolution of Apollo butterflies [PDF]

Systematic Biology, 2017
AbstractIn macroevolution, the Red Queen (RQ) model posits that biodiversity dynamics depend mainly on species-intrinsic biotic factors such as interactions among species or life-history traits, while the Court Jester (CJ) model states that extrinsic environmental abiotic factors have a stronger role.
