Maximum human visual SENSITIVITY under photopic (daylight) conditions) is about 555 nm...almost exactly the yellow that fireflies produce.
Under scotopic conditions (Night-time) it drops to 500nm. more orange. True, there is more energy in blue light than red light... and there is more energy in UV than in blue but we can't see it. I don't think ACUITY enters into it.
