Photoreceptor spectral sensitivity in the bumblebee, Bombus impatiens (Hymenoptera: Apidae).

The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour. However, full spectral sensitivity data on the photoreceptor inputs underlying colour vision are not available for B. impa...
