Heliconiines are called passion vine butterflies because they feed exclusively on Passiflora plants during the larval stage. Many features of Passiflora and heliconiines indicate that they have radiated and speciated in association with each other, and therefore this model system was one of the first examples used to exemplify coevolution theory. Three major adaptations of Passiflora plants supported arguments in favour of their coevolution with heliconiines: unusual variation of leaf shape… 
Sequestration and biosynthesis of cyanogenic glucosides in passion vine butterflies and consequences for the diversification of their host plants
The CNglc distribution within Passiflora suggests that they might have diversified their cyanogenic profile to escape heliconiine herbivory, and improves the understanding on the evolution of cyanogenesis in the heliconiinae–PassiflorA system.
Sequestration and functional diversification of cyanogenic glucosides in the life cycle of Heliconius melpomene
How the CNglc composition and expression of the putative P450s involved in the biosynthesis of these compounds vary at different development stages of Heliconius butterflies is determined and shed light on the importance of CNglcs in Heliconii biology and for their coevolution with Passiflora.
High evolutionary potential in the chemical defenses of an aposematic Heliconius butterfly
This work investigates variation in biosynthesized toxicity both in wild populations along environmental gradients and in common-garden broods and feeding treatments in Heliconius erato, together demonstrating considerable intraspecific variation and evolutionary potential in this important chemical defense trait.
Assessing the Role of Developmental and Environmental Factors in Chemical Defence Variation in Heliconiini Butterflies
The results show significant differences in both the amount of synthesized and sequestered compounds between butterflies reared in captivity and those collected in the field, and highlight the overlooked effect of synthesis capabilities, which may be genetically determined to some extent.
A peculiar new species of Dione (Agraulis) Boisduval & Le Conte (Lepidoptera, Nymphalidae, Heliconiinae) associated with Malesherbia Ruiz & Pavón (Passifloraceae) in xeric western slopes of the Andes
D. Don (Passifloraceae) found in xeric environments, representing a new record of this genus as a host plant for the subfamily Heliconiinae, is found, and conspicuous morphological differences are presented for all stages at the generic level.
A genome sequence resource for the genus Passiflora, the genome of the wild diploid species Passiflora organensis
This study presents the first draft genome assembly of a wild Passiflora species, providing a valuable sequence resource for genomic and evolutionary studies on the genus, and support for breeding cropped passionfruit species.
Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly
This work studied intraspecific variation in de novo biosynthesized cyanogenic toxicity and its potential ecological and evolutionary sources in wild populations of Heliconius erato along environmental gradients, in common-garden broods and with feeding treatments, and highlights the extensive variation and potential for adaptive evolution in defense traits for aposematic and mimetic species.
The effect of insect cyanoglucosides on predation by domestic chicks

Support is provided for cyanoglucosides as defensive chemicals of aposematic lepidopterans and related arthropods by the rejection of cyanide laced prey, which suggests that some species that store aromatic cyanoglUCosides could be detected via smell as well by taste.
The effect of cyanogenic glucosides and their breakdown products on predation by domestic chicks
Support is provided for cyanoglucosides as defensive chemicals of aposematic lepidopterans and related arthropods by rejection of cyanide-laced prey and the rejection of the pungent but not toxic benzaldehyde and the potential effect of acetone suggest that cyanoglucaosides could be detected via smell as well by taste.


Only Attract Ants? The Versatility of Petiolar Extrafloral Nectaries in Passiflora
A more active role is suggested in the modulation of the gland defense from plants besides the establishment of a mutualistic relationship with ants, an important response in a coevolutive scenario.
The transcriptome response of Heliconius melpomene larvae to a novel host plant
It is suggested that transcriptional plasticity of genes in a herbivore may play an important role in adaptation to a new host plant.
A hypothesis as to just how coevolution between insects and plants in the past resulted in these present day patterns was suggested by Brues (1920) and developed fully by Ehrlich and Raven (1965) on the basis of butterfly host plant data.
Ant protection against herbivores and nectar thieves in Passiflora coccinea flowers
A protective role of ants for flowers of Passiflora coccinea is suggested, improving plant reproductive success and possible fitness benefits for the plant resulting from the presence of ants.
Defense and carnivory: Dual role of bracts inPassiflora foetida
Results suggest a novel role for bracts where primary function is to minimize predatory damage to developing flowers and fruits and the mechanism to digest the trapped insects to obtain free aminoacids.
Cyanogenesis in plants and arthropods.
Effects of Cyanogenesis Polymorphism in Turnera ulmifolia on Euptoieta hegesia and Potential Anolis Predators
It is provided that the presence of sequestered cyanogenic compounds in the larvae protects them from terrestrial-based predators such as Anolis lizards, and indicates that larvae are capable of sequestering cyanogenic glycosides from their host plants and possibly of synthesizing these or similar compounds.
The Proposed Anti-herbivory Roles of White Leaf Variegation
It has been suggested that white variegation, the outcome of various developmental, genetic, and physiological processes, may defend leaves and other plant organs from herbivory by several proposed
