Behavioral sensitivities to the stimulus wavelengths of light of individuals grown under green light (N = 5) and those grown under orange light (N = 5) at various wavelengths. The behavioral sensitivity was calculated as the negative logarithm of threshold detectable light intensities (μmol/m²/s) according to optomotor responses (see Methods section). Circles indicate the means ± standard errors of the mean (SEM)
