The article doesn't mention this but as I understand flies can only see motion. So when you move very slow you can catch them.
It doesn't mean that they only see moving objects by the way. In flight they see because everything is moving around them.
- zeotroph 9y agoI thought that most (all?) eyes only see motion, just as you do not feel the weight of your clothes anymore (or the presence/absense of your wallet in your back pocket) after a while. But reading up on microsaccades[1] - tiny involuntary eye movements which I thought fixed that in mammals - that does not seem to be the current understanding anymore. 1: https://en.wikipedia.org/wiki/Microsaccade https://en.wikipedia.org/wiki/Microsaccade
