Allen Dick added:
Motion seems to play a large role in what bees 'see'. It seems to me that
when motion is involved, bees are able to use the additional information
generated by motion to enhance (over time) what we imagine they 'see' from
considering the static image inputs.

Both Dave and Allen hit the nail on the head. Despite all our
rinky-dinky experiments, we still know VERY little about what insects
see. For instance, I have noticed that fast moving honey bees that
approach a cyclone (chain link) fence go up and over it, even though
they could very well fly right through the openings.
By contrast, I have seen dragonflies (with reputedly superior
eyesight) fly right into cyclone fences.
