1. Limitations to spatial resolution in the ventral refracting superposition eye of the crepuscular dung beetle, Onitis alexis, were investigated using intracellular electrophysiological recordings and optical modelling. 2. The measured angular-sensitivity functions for Onitis are narrow compared to many superposition eyes, but display considerable off-axis flanks, or flare. These flanks are reduced as the eye becomes light adapted, but the acceptance angle remains constant at about 4°, both… CONTINUE READING
