Sexual Dimorphism of Short-Wavelength Photoreceptors in the Small White Butterfly, Pieris rapae crucivora
TLDR
The eyes of the female small white butterfly, Pieris rapae crucivora, are furnished with three classes of short-wavelength photoreceptors, with sensitivity peaks in the ultraviolet (UV), violet, and blue (B) wavelength range, which are termed PrUV, PrV, and PrB.
Evolution and Mechanism of Spectral Tuning of Blue-Absorbing Visual Pigments in Butterflies
TLDR
To reveal accurate absorption profiles and the molecular basis of the spectral tuning of these visual pigments, this work successfully modified the honeybee opsin expression system based on HEK293s cells, and expressed PrB and PrV, the first lepidopteran opsins ever expressed in cultured cells.
Spectral heterogeneity of honeybee ommatidia
TLDR
The expression patterns of the three opsin mRNAs demonstrated that three distinct types ommatidia exist, refuting the common assumption that the o mmatidia composing the bee compound eye contain identical sets of spectral receptors.
A unique visual pigment expressed in green, red and deep-red receptors in the eye of the small white butterfly, Pieris rapae crucivora
TLDR
In situ hybridization of the opsin mRNA of the novel visual pigment (PrL) demonstrated that it is expressed in the two distal photoreceptor cells (R3 and R4) as well as in the proximal photoreceptors (R5–8) in all three types of ommatidia of the Pieris eye.
Evolution of color vision in pierid butterflies: blue opsin duplication, ommatidial heterogeneity and eye regionalization in Colias erate
TLDR
This paper documents the molecular organization of the eye of the Eastern Pale Clouded Yellow butterfly, Colias erate (Pieridae), and localized the opsin mRNAs in the Colias retina by in situ hybridization.
Coexpression of three middle wavelength-absorbing visual pigments in sexually dimorphic photoreceptors of the butterfly Colias erate
The tiered ommatidia of the Eastern Pale Clouded yellow butterfly, Colias erate, contain nine photoreceptor cells, four of which contribute their rhabdomeral microvilli to the distal tier of the
Opsin expression, physiological characterization and identification of photoreceptor cells in the dorsal rim area and main retina of the desert locust, Schistocerca gregaria
TLDR
The data support the role of the DRA in polarization vision and suggest trichromatic colour vision in the desert locust, as well as suggesting a nocturnal lifestyle at low light levels.
Relationship between Action Spectrum and Spectral Sensitivity of Compound Eyes Relating Phototactic Behavior of the Western Flower Thrips, Frankliniella occidentalis
TLDR
In a choice experiment where the insects were subjected to select either 355 nm or 525 nm of equal photon flux, they preferred 355 nm to 525 nm, indicating that the insects prefer ultraviolet (UV) radiation under the condition of multiple light sources.
Spectral Organization of Ommatidia in Flower‐visiting Insects †
TLDR
The organization of the compound eye in lepidopteran and hymenopteran insects is basically retained, although some butterflies have more than six classes of spectral receptors, including those sensitive in the violet and red wavelength regions.
