The evolution of color vision in insects.
We review the physiological, molecular, and neural mechanisms of insect color vision. Phylogenetic and molecular analyses reveal that the basic bauplan, UV-blue-green-trichromacy, appears to dateExpand

Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferringExpand

Insect cryptochromes: gene duplication and loss define diverse ways to construct insect circadian clocks.
Cryptochrome (CRY) proteins are components of the central circadian clockwork of metazoans. Phylogenetic analyses show at least 2 rounds of gene duplication at the base of the metazoan radiation, asExpand

Connecting the Navigational Clock to Sun Compass Input in Monarch Butterfly Brain
Migratory monarch butterflies (Danaus plexippus) use a time-compensated sun compass to navigate to their overwintering grounds in Mexico. Although polarized light is one of the celestial cues usedExpand

Female Behaviour Drives Expression and Evolution of Gustatory Receptors in Butterflies
Secondary plant compounds are strong deterrents of insect oviposition and feeding, but may also be attractants for specialist herbivores. These insect-plant interactions are mediated by insectExpand

The two CRYs of the butterfly
(Current Biology 15, R953–R954; December 6, 2005) The authors wish to correct an omission in this Correspondence. Dr. Adriana D. Briscoe should be a coauthor for this paper, because she was the firstExpand

SUMMARY The eyes of butterflies are remarkable, because they are nearly as diverse as the colors of wings. Much of eye diversity can be traced to alterations in the number, spectral properties andExpand

Positive selection of a duplicated UV-sensitive visual pigment coincides with wing pigment evolution in Heliconius butterflies
The butterfly Heliconius erato can see from the UV to the red part of the light spectrum with color vision proven from 440 to 640 nm. Its eye is known to contain three visual pigments, rhodopsins,Expand

Not all butterfly eyes are created equal: Rhodopsin absorption spectra, molecular identification, and localization of ultraviolet‐, blue‐, and green‐sensitive rhodopsin‐encoding mRNAs in the retina
Surveys of spectral sensitivities, visual pigment spectra, and opsin gene sequences have indicated that all butterfly eyes contain ultraviolet‐, blue‐, and green‐sensitive rhodopsins. Some speciesExpand

Color discrimination in the red range with only one long-wavelength sensitive opsin
SUMMARY The basic precondition for color vision is the presence of at least two receptor types with different spectral sensitivities. The sensitivity of a receptor is mostly defined by theExpand
