An ultraviolet absorbing pigment causes a narrow-band violet receptor and a single-peaked green receptor in the eye of the butterfly Papilio An ultraviolet absorbing pigment causes a narrow-band violet receptor and a single-peaked green receptor in the eye of the butterfly Papilio 蟻川, 謙太郎 ARIKAWA, Kentaro MIZUNO, Shin SCHOLTEN, D. G W KINOSHITA, Michiyo SEKI, Takaharu KITAMOTO, Junko STAVENGA, Doekele G The distal photoreceptors in the tiered retina of Papilio exhibit different spectral sensitivities. There are at least two types of short-wavelength sensitive receptors: an ultraviolet receptor with a normal spectral shape and a violet receptor with a very narrow spectral bandwidth. Furthermore, a blue receptor, a double-peaked green receptor and a single-peaked green receptor exist. The violet receptor and single-peaked green receptor are only found in ommatidia that fluoresce under ultraviolet illumination. About 28% of the ommatidia in the ventral half of the retina exhibit the UV-induced fluorescence. The fluorescence originates from an ultraviolet-absorbing pigment, located in the most distal 70 μm of the ommatidium, that acts as an absorption filter, both for a UV visual pigment, causing the narrow spectral sensitivity of the violet receptor, and for a green visual pigment, causing a single-peaked green receptor. journal article Elsevier 1999-01 Vision Research 1 39 1 8 Vision Research 00426989 https://ir.soken.ac.jp/records/3619 eng 10211390 10.1016/S0042-6989(98)00070-4 http://doi.org/10.1016/S0042-6989(98)00070-4 © 1998 Elsevier Science Ltd. metadata only access
