Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways. [PDF]

Adv Sci (Weinh)
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

The Coevolution of Colour Patterns and Hindwing Shapes on a Large Phylogenetic Scale Reveals Predation-Driven Adaptive Syndromes in Swallowtail Butterflies. [PDF]

Ecol Lett
By combining computer vision and morphometrics on museum specimens, we show that hindwing tail shape and colour patterns evolved in concert across swallowtails. Long‐tailed species display contrasted stripes and marginal spots, suggesting coevolution of deflective traits promoted by natural selection by predators.

Predictors of Wing Attacks by Birds Across Australian Butterflies. [PDF]

Ecol Evol
Predation pressure can vary latitudinally and across different prey communities as well as between males and females of the same prey species. Here, the variation in predation pressure on Australian butterflies was assessed using wing damage caused by bird attacks in over 2310 individuals from five butterfly families.

Evolutionary Changes of <i>GT1</i> Provide Insights Into the Adaptation of Butterflies to Plant Feeding. [PDF]

Ecol Evol
We investigated the evolution of glycosyltransferase 1 (GT1) genes in 69 butterfly species to explore their association with host plant adaptation. Our results reveal frequent tandem duplications and adaptive selection in GT1s, especially in UGT33 and UGT40 subfamilies, alongside expression patterns suggesting functional diversification.

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness. [PDF]

Am J Bot
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Puddling by Female Florida Tiger Swallowtail Butterflies, \u3ci\u3ePapillo Glaucus Australis\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

, 2017
(excerpt) Many species from all families of Rhopaloccra have been reported to drink water (Norris 1936). Bates (1863) noted that, in the Amazon, 80 species from 22 genera flocked about the damp edges of water and, with very few exceptions, all of these ...

Variation of thorax flight temperature among twenty Australian butterflies (Lepidoptera: Papilionidae, Nymphalidae, Pieridae, Hesperiidae, Lycaenidae)

European Journal of Entomology, 2016
Thermal requirements for flight in butterflies is determined by a combination of external factors, behaviour and physical constraints. Thorax temperature of 152 butterflies was monitored with an infra-red thermometer in controlled laboratory conditions ...

The complete mitochondrial genome of the Papilio memno (Lepidoptera:Papilionidae)

Mitochondrial DNA. Part B. Resources, 2020
In this study, the mitochondrial genome (mitogenome) sequence of Papilio memno is determined using next-generation sequencing. The entire mitogenome genome is determined to be 15,262 bp in length.

Biogeographical patterns of the neotropical genus Battus Scopoli 1777 (Lepidoptera Papilionidae) [PDF]

, 1993
A phylogenetic approach to the groups of species of the neotropical Troidines currently included in the genus Battus Scopoli 1777 has been conducted. In the light of historical and ecological processes of evolution in the neotropical biota, the cladogram

Foodplant Processing Adaptations in Four \u3ci\u3eHyalophora\u3c/i\u3e Species (Lepidoptera: Saturniidae): Regional and Taxonomic Specialization [PDF]

, 2017
To determine whether local populations of four Hyalophora species (Lepidoptera: Satumiidae) had improved survival or were physiologically adapted for rapid and/or efficient growth on their local hosts, a series of larval feeding studies were conducted ...
