Sex-specific morphs exhibit discrete phenotypes, often including many disparate traits, that
are observed in only one sex. These morphs have evolved independently in many different …

Highlights•Examples of pigments and waxes associated with coloration in Odonata are
reviewed.•Genes involved in the biosynthesis pathway of three major pigments in Odonata …

Insect distributions are shifting rapidly in response to climate change and are undergoing
rapid evolutionary change. We investigate the molecular signatures underlying local …

The diversity in the color patterns of butterfly wings is one of the most spectacular and
mysterious puzzles of and unsolved problems in nature. Most of the 15,000 or so species of …

Animal colours commonly act as signals for mates or predators. In many damselfly species,
both sexes go through a developmental colour change as adults, and females often show …

The evolution of sex chromosomes, and patterns of sex-biased gene expression and
dosage compensation, are poorly known among early winged insects such as odonates. We …

Odonata species display a remarkable diversity of colour patterns, including intrasexual
polymorphisms. In the damselfly (Ischnura senegalensis), the expression of a sex …

We present a genome assembly from an individual female Ischnura elegans (the blue-tailed
damselfly; Arthropoda; Insecta; Odonata; Coenagrionidae). The genome sequence is 1,723 …

Sexual dimorphism occurs widely throughout insects and has profound influences on
evolutionary path. Sex-biased genes are considered to account for most of phenotypic …

Many species are currently changing their distributions and subsequently form sympatric
zones with hybridization between formerly allopatric species as one possible consequence …
