Do Roly Poly's eat plants?

This morning I noticed a kush with eaten leaves. Looked for catipillars with no luck. Then noticed more in more leaves that were eaten on the inside and a bunch of roly polys on leaves and more traveling on the stems. When I first seen em days ago.. I figured they eat lil bugs.. now not so sure.. always liked them.. now maybe they be enemy #2 for me, after mites of course!

They eat animal waste like a dung beetle.

OK, thanks. Wonder what animal waste is in the plants? The mites that are loosing their battle with me? this morning I still had some of them up in my plants. Oh well, as long as they dont harm the plants, let em wander..

Actually they eat decaying plant matter, like earthworms do. These are probably climbing your plant on a dare ... "bring back a big trichome, Woody, and yer in the club!! Then we'll party like DRAGONFLIES!!!"
seriously, i don't think they're something to worry about.
