Simple Summary Many animals, including insects, evolved sensitivity to ultraviolet light (UV).
The presence of UV photoreceptors in the visual systems of many animals shows that UV …

Color is an important communication channel for day-flying butterflies. Chemical
(pigmentary) coloration is often supplemented by physical color generated by photonic …

Sexually dimorphic development is responsible for some of the most remarkable phenotypic
variation found in nature. Alternative splicing of the transcription factor gene doublesex (dsx) …

Viability indicator traits are expected to be integrated extensively across the genome yet sex-
limited to ensure that any benefits are sexually concordant. Understanding how such …

Digitising a collection is key to make it last even after the physical objects are no longer
available. Almost all of the techniques currently available to digitise a natural history …

Iridescent ultraviolet (IUV) patterns on pierid butterfly wings are phenotypic adaptations
commonly used as sexual signals, generated by scales with ultrastructural modifications …

The aim of this book is to present a readable account of butterfly behaviour, based on field
observations, great photographs and the latest research. The main focus is on courtship and …

The term 'cryptic'species refers to pairs of species with no clear morphological differences
that could have been delimited from one another only with molecular tools (Knowlton 1993; …

Seasonal variation of color patterns on butterfly wings are iconic examples of
developmentally plastic traits that can influence adaptation and speciation. Yet, there are …

Lepidoptera (scaled-wing) are named after the scales on their wings. These scales are an
innovation that gives Lepidoptera access to a very large color space beyond our human …
