Locusts aren't a separate species, they are just regular grasshoppers that physically transform when overcrowded.This biological phenomenon is known as phase polyphenism.When resources shrink and grasshoppers are forced together, constant physical contact rubs their hind legs. This tactile stimulation triggers a massive spike in serotonin, which drives a radical transformation within just a few hours.They shift from camouflaged green to bright, warning colors like yellow, black, and orange.They also develop longer wings, stronger flight muscles, smaller mature bodies, and larger brains.Science and facts💡
