title: Spectral sensitivity and wing colors of Narathura and Panchala species.
abstract: Spectral sensitivity and wing colors were compared among three species of lycaenid butterflies, Panchala ganesa, Narathura bazalus and Narathura japonica. Spectral sensitivity was examined by the ERG method using an integrating sphere which could stimulate the whole surface of the compound eye. Wing colors were measured using a spectrophotometer. All three species examined were sensitive to a broad wavelength range, from UV to red light, with the primary peak in the shorter wavelength region. Slight peak shifts were observed among the studied species; species with wings reflecting shorter wavelength light tended to be sensitive to shorter wavelength lights.
