Abstract

Abstract This chapter aims to discuss what do bees detect with their eyes, and wants to show that a simple neuron interaction yields a useful cue and that behaviour can be correlated with neuron types. A symbolic representation of cue structure is also given. This chapter also defines the visual world of the bee, and other arthropods. With similar primary visual inputs, bees have a totally different visual world. They measure total inputs in each input channel, they detect contrast multiplied by edge length to measure modulation. They total the optic flow to measure distance flown and scan modulation to detect asymmetry. They detect horizontal position of blue relative to a green contrast, and its polarity. The cues are partially independent of range, but a far cry from the vision of higher vertebrates.
