Bumblebees learned to tell short and long light flashes apart, showing they can process time like Morse code.
Bumblebees have learned to distinguish between short and long flashes of light, akin to Morse code, according to a study by Queen Mary University of London.
Trained to associate specific durations with sugar or quinine, bees chose correct patterns 15 out of 20 times and maintained choices even without rewards, proving they relied on timing, not scent or location.
This marks the first evidence of such temporal discrimination in insects, suggesting a hidden capacity for time processing likely evolved for navigation or movement tracking.
The findings challenge the notion that complex cognition requires large brains and highlight unexpected mental abilities in small-brained animals.
The study was published in Biology Letters.
