The flicker fusion threshold also varies between species. A 2014 survey of the critical fusion frequency in animals found the lowest value (6.7 Hz) in the cane toad (Bufo marinus) and the highest value (400 Hz) in the black fire beetle (Melanophila acuminate). [22]
Since bandy-bandys are nocturnal, they can effective execute this illusion by moving fast in dim light. The 'flicker fusion' effect only works to confuse predators if its frequency exceeds that of the predators' critical fusion frequencies (CFFs) in their eyes. Bandy-bandys can exceed this effect higher than most vertebrates' CFFs and thus ...
Peregrine falcons have a flicker fusion frequency of 129 Hz (cycles per second), very fast for a bird of its size, and much faster than mammals. [60] A study testing the flight physics of an "ideal falcon" found a theoretical speed limit at 400 km/h (250 mph) for low-altitude flight and 625 km/h (388 mph) for high-altitude flight. [61]

"The maximum fusion frequency for rod-mediated vision reaches a plateau at about 15 Hz." "Cones reach a plateau [...] of about 60 Hz" "The rod cells of the human eye have a faster response time than the cone cells, so flicker can be sensed in peripheral vision at higher frequencies than in foveal vision."

If the modulation frequency is below the flicker fusion threshold and if the magnitude of the TLM exceeds a certain level, then such TLMs are perceived as flicker. Light modulations with modulation frequencies beyond the flicker fusion threshold are not directly perceived, but illusions in the form of stroboscopic effect may become visible ...
