Ants and Colors.

It was proved long ago that ants have the power of seeing the—to us — invisible rays of the ultra violet portion of the spectrum., They fear the light for their larvae and when allowed choice between different degrees* of light always carry them to the darkest place accessible. When given the choice between a compartment lighted with yellow light and one dark to our eyes, but under the actinic ray, the ants unhesitatingly chose the yellow light, showing that to their ’eyes it was darker than the other, to man Invisible.—Argonaut. ,
