Although dragonflies and damselflies (Insecta: Odonata) represent some of the most
advanced visual systems among insects, odonate visual systems are not as well understood …

Negative frequency-dependent selection (NFDS) is one of the most powerful selective forces
maintaining genetic polymorphisms in nature. Recently many prospective cases 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 …

Conspicuous male colouration is expected to have evolved primarily through selection by
female choice. In what way conspicuous colours could be advantageous to males …

Background There is growing interest in odonates (damselflies and dragonflies) as model
organisms in ecology and evolutionary biology but the development of genomic resources …

Many invertebrate species show conspicuous colour polymorphisms, the study of which has
provided us with important insights in evolutionary biology. The potential importance of …

Animal communication relies on conspicuous signals and compatible signal perception
abilities. Good signal perception abilities are particularly important for polymorphic animals …

Dimorphic traits are ubiquitous in nature, but the evolutionary factors leading to dimorphism
are largely unclear. We investigate a potential case of sexual mimicry in Drosophila erecta …

Current research on female colour polymorphism in Ischnura damselflies suggests that a
balanced fitness trade-off between morphotypes contributes to the maintenance of …

Sexual signalling using dynamic skin colouration is a key feature in some vertebrates;
however, it is rarely studied in amphibians. Consequently, little is known about the hormonal …
