Oh yeah. Ants are just great no matter where you fish them in the water column. I have caught fish before on top with foam ants/beetles, then taken the same foam fly and added enough split shot to sink it and caught fish out of the same spot on the bottom. It takes a lot of shot to really sink a foam ant or beetle, but they simply catch fish anywhere from the surface to the bottom. Its fun to play around with them and try different things.
