    No.  Their eyes rely on visible light.  In fact, they see less of what we call "visible light" than we do.  Our eyes pick up lower light frequencies than theirs do - they can't see red.  Isn't it strange then that they always go straight for the tomatoes?  (They CAN tell between polarized and unpolarized light, though - which we can't.)

    A lab in Japan has been raising fruit flies in total darkness for 60 years, in the hope of monitoring the effect that has on their DNA.  (Since their lives are brief, 60 years is thousands of generations.)  Obviously, it wouldn't make much sense to choose darkness as the stressor in that experiment if they could see in the dark.
