New localities for Heliconius besckei Ménétriés and Heliconius sara (Fabricius) (Lepidoptera: Nymphalidae) in Bahia, Brazil [PDF]

open access: yesNeotropical Entomology, 2005
New occurrences for two Heliconius Kluk species are reported for sites in inland Bahia, Brazil. New inland sites are reported for Heliconius sara (Fabricius), a species normally found at coastal regions. To our knowledge, Heliconius besckei Menetries, a species restricted to cool mountain habitats, is reported for Northeastern Brazil for the first time.

Evolutionary Novelty in a Butterfly Wing Pattern through Enhancer Shuffling.

open access: yesPLoS Biology, 2016
An important goal in evolutionary biology is to understand the genetic changes underlying novel morphological structures. We investigated the origins of a complex wing pattern found among Amazonian Heliconius butterflies.

Butterfly Learning and the Diversification of Plant Leaf Shape

open access: yesFrontiers in Ecology and Evolution, 2016
Visual cues are important for insects to find flowers and host plants. It has been proposed that the diversity of leaf shape in Passiflora vines could be a result of negative frequency dependent selection driven by visual searching behavior among their ...

Clustering of loci controlling species differences in male chemical bouquets of sympatric Heliconius butterflies

open access: yesEcology and Evolution, 2021
The degree to which loci promoting reproductive isolation cluster in the genome—that is, the genetic architecture of reproductive isolation—can influence the tempo and mode of speciation.

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

open access: yesJournal of Fish Biology, Volume 108, Issue 5, Page 1429-1443, May 2026.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

The evolution and development of structural colour in Heliconius butterflies [PDF]

open access: yes, 2022
In nature, nanostructures can interact with light to produce a striking array of colours called structural colours. Such colours have gained considerable attention in evolutionary biology and, more recently, as potential routes for the design of ...

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Longwing (Heliconius) butterflies combine a restricted set of pigmentary and structural coloration mechanisms

open access: yesBMC Evolutionary Biology, 2017
Background Longwing butterflies, Heliconius sp., also called heliconians, are striking examples of diversity and mimicry in butterflies. Heliconians feature strongly colored patterns on their wings, arising from wing scales colored by pigments and/or ...
