Abstract Pancrustacea (Hexapoda plus Crustacea) display an enormous diversity of eye
designs, including multiple types of compound eyes and single-chambered eyes, often with …

The visual pigments known as opsins are the primary molecular basis for colour vision in
animals. Insects are among the most diverse of animal groups and their visual systems …

Vertebrate vision is accomplished through light-sensitive photopigments consisting of an
opsin protein bound to a chromophore. In dim light, vertebrates generally rely on a single …

The Colorado potato beetle is one of the most challenging agricultural pests to manage. It
has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable …

Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful
model organism for the study of generalized insect development, and an important pest of …

Background Relatively little is known about the genomic basis and evolution of wood-
feeding in beetles. We undertook genome sequencing and annotation, gene expression …

The bed bug, Cimex lectularius, has re-established itself as a ubiquitous human
ectoparasite throughout much of the world during the past two decades. This global …

There has been a recent trend in evolutionary developmental biology (evo–devo) towards
using increasing numbers of model species. I argue that, to understand phenotypic change …

Opsin proteins are fundamental components of animal vision whose structure largely
determines the sensitivity of visual pigments to different wavelengths of light. Surprisingly …

Independent evolution has resulted in a vast diversity of eyes. Despite the lack of a common
Bauplan or ancestral structure, similar developmental strategies are used. For instance …
