Fig. 4From: Red-shift of spectral sensitivity due to screening pigment migration in the eyes of a moth, Adoxophyes orana ERG-determined compound eye spectral sensitivities of male Adoxophyes orana. a Averaged light-adapted spectral sensitivities of individuals from Nagano (n = 8), Niigata (10), Akita (4) and Aomori (7) strains. b Dark- and light-adapted spectra recorded from the same Niigata individuals (n = 2), to measure the change in absolute sensitivity in the light-adapted state. The dotted spectrum shows the light-adapted spectrum expanded vertically (scale on the right). c Same as b, for the Nagano strain (n = 1)Back to article page
