They both perform well in simulated environments.
As Richard wrote in his post 'New Behavioural Rig' from 3/22/2020, we now have the ability to record behavioural data from tethered flights while hoverflies view stimuli on 3 surrounding screens. The below pictures show the high tech simulators used in the current Supercars Eseries, which is basically a closed loop behavioural rig with multiple users.
While there were only 5 of us watching the first hoverfly tethered flight on the behavioural rig, the first race of the Supercars Eseries attracted an estimated 158,000 viewers. The equipment involves in the Eseries can cost over $100,000, its probably no surprise that the lab's behavioural rig cost a lot less. The Eseries will take its drivers virtually to over 4 continents and 9 countries. So far our hoverflies have been shown only a few visual stimuli, they definitely haven't virtually flown in France, America or even at the legendary Mount Panorama.
