Major patterns in the introgression history of Heliconius butterflies [PDF]

open access: goldeLife, 2023
Gene flow between species, although usually deleterious, is an important evolutionary process that can facilitate adaptation and lead to species diversification. It also makes estimation of species relationships difficult.

The roles of hybridization and habitat fragmentation in the evolution of Brazil’s enigmatic longwing butterflies, Heliconius nattereri and H. hermathena [PDF]

open access: goldBMC Biology, 2020
Background Heliconius butterflies are widely distributed across the Neotropics and have evolved a stunning array of wing color patterns that mediate Müllerian mimicry and mating behavior.

Adult neurogenesis does not explain the extensive post-eclosion growth of Heliconius mushroom bodies [PDF]

open access: yesRoyal Society Open Science, 2023
Among butterflies, Heliconius have a unique behavioural profile, being the sole genus to actively feed on pollen. Heliconius learn the location of pollen resources, and have enhanced visual memories and expanded mushroom bodies, an insect learning and ...

Heliconius butterflies use wide-field landscape features, but not individual local landmarks, during spatial learning [PDF]

open access: yesRoyal Society Open Science
Spatial learning is vital in foraging ecology. Many hymenopteran insects are adept spatial foragers that rely on visual cues contained within broader wide-field scenes for central place foraging from a central nest.

Estimating the age of Heliconius butterflies from calibrated photographs [PDF]

open access: goldPeerJ, 2017
Mating behaviour and predation avoidance in Heliconius involve visual colour signals; however, there is considerable inter-individual phenotypic variation in the appearance of colours.

Enhanced long-term memory and increased mushroom body plasticity in Heliconius butterflies [PDF]

open access: yesiScience
Summary: Heliconius butterflies exhibit expanded mushroom bodies, a key brain region for learning and memory in insects, and a novel foraging strategy unique among Lepidoptera – traplining for pollen.

Complex interspecific and intersexual patterns of wing design in Heliconius butterflies [PDF]

open access: goldNota Lepidopterologica
In butterflies, interspecific and intersexual variation in wing design morphology modifies aerodynamic efficiency and individuals’ flight costs. Wing design involves traits like wing shape and size, which determine flight performance and behavioral ...

Using motion‐detection cameras to monitor foraging behaviour of individual butterflies [PDF]

open access: yesEcology and Evolution
The activity of many animals follows recurrent patterns and foraging is one of the most important processes in their daily activity. Determining movement in the search for resources and understanding temporal and spatial patterns in foraging has ...

Genomic evidence reveals three W-autosome fusions in Heliconius butterflies. [PDF]

open access: yesPLoS Genetics
Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes and autosomes have been proposed to reduce sexual conflict and to promote adaptation and ...

Is beauty beyond the eye of the butterfly? [PDF]

open access: yesPLoS Biology
The bright colors observed across the animal world are often used during mate choice. An exciting new study in PLOS Biology suggests genetic and neural mechanisms contributing to the evolution of visual mating decisions in Heliconius butterflies.
