Sex pheromones in many insect species are important species-recognition signals that
attract conspecifics and inhibit attraction between heterospecifics; therefore, sex …

Pheromones are chemical signals that facilitate communication between animals, and most
animals use pheromones for reproduction and other forms of social behavior. The …

In true color vision, animals discriminate between light wavelengths, regardless of intensity,
using at least two photoreceptors with different spectral sensitivity peaks. Heliconius …

Comparative studies of related but ecologically distinct species can reveal how the nervous
system evolves to drive behaviors that are particularly suited to certain environments …

Many animal species remain separate not because their individuals fail to produce viable
hybrids but because they “choose” not to mate. However, we still know very little of the …

Neotropical Heliconius butterflies are well known for their intricate behaviors and multiple
instances of incipient speciation. Chemosensing plays a fundamental role in the life history …

The Ornate Moth, Utetheisa ornatrix, has served as a model species in chemical ecology
studies for decades. Like in the widely publicized stories of the Monarch and other milkweed …

In organisms reproducing sexually, speciation occurs when increasing divergence results in
pre‐or post‐zygotic reproductive isolation between lineages. Studies focusing on …

Heliconius butterflies have undergone adaptive radiation and therefore serve as an
excellent system for exploring the continuum of speciation and adaptive evolution. However …

Butterflies have become prominent models for studying the evolution and development of
phenotypic variation. In Heliconius, extraordinary within species divergence and between …
