Simple exponential functions describing the absorbance bands of visual pigment spectra
Literature data for visual pigment spectra are formally treated by assuming that the spectra consist of a summation of absorbance bands, that the shape of the bands is invariant according to theExpand

Sexual Dimorphism of Short-Wavelength Photoreceptors in the Small White Butterfly, Pieris rapae crucivora
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) (λmax = 360Expand

Pseudopupils of Compound Eyes
“I come to the discussion of a remarkable optical phenomenon the unravelling of which has caused me a good deal of worry.” In this way Sigmund Exner (1891, p. 162) begins the chapter on pseudopupilsExpand

Light on the moth-eye corneal nipple array of butterflies
The outer surface of the facet lenses in the compound eyes of moths consists of an array of excessive cuticular protuberances, termed corneal nipples. We have investigated the moth-eye corneal nippleExpand

Refractive index and dispersion of butterfly chitin and bird keratin measured by polarizing interference microscopy.
Using Jamin-Lebedeff interference microscopy, we measured the wavelength dependence of the refractive index of butterfly wing scales and bird feathers. The refractive index values of the glass scalesExpand
