Modality-specific long-term memory enhancement in Heliconius butterflies. [PDF]
Philos Trans R Soc Lond B Biol SciHow animals perceive, process and respond to environmental cues is tightly tuned to species-specific ecological demands and reflected by the structure of neural systems. In the Neotropical butterflies, Heliconius, the mushroom bodies, insect learning and

Data from: Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
, 2015 The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferring beneficial traits between species. Here we use genomic tools to

Estimation of the Spontaneous Mutation Rate in Heliconius melpomene [PDF]
Molecular Biology and Evolution, 2014 We estimated the spontaneous mutation rate in Heliconius melpomene by genome sequencing of a pair of parents and 30 of their offspring, based on the ratio of number of de novo heterozygotes to the number of callable site-individuals. We detected nine new mutations, each one affecting a single site in a single offspring.

BMC Evolutionary Biology, 2010 Background Protein-coding change is one possible genetic mechanism underlying the evolution of adaptive wing colour pattern variation in Heliconius butterflies. Here we determine whether 38 putative genes within two major Heliconius patterning loci, HmYb

Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly [PDF]
PeerJ, 2021 Chemical defences against predators underlie the evolution of aposematic coloration and mimicry, which are classic examples of adaptive evolution. Surprisingly little is known about the roles of ecological and evolutionary processes maintaining defence ...

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

The Scent Chemistry of Heliconius Wing Androconia
Journal of Chemical Ecology, 2017 Neotropical Heliconius butterflies are members of various mimicry rings characterized by diverse colour patterns. In the present study we investigated whether a similar diversity is observed in the chemistry of volatile compounds present in male wing androconia. Recent research has shown that these androconia are used during courting of females.

Mushroom body expansion and the cognitive ecology of Heliconius butterflies
, 2022 Heliconius butterflies, a Neotropical genus of approximately 50 species, exhibit a marked expansion of an insect brain structure called the mushroom bodies (MBs), which are 3-4 times larger than in other Lepidoptera, including closely related Heliconiini
