Is a roly poly a herbivore carnivore or both?

A roly poly, also known as a pillbug or woodlice, is primarily a detritivore, meaning it feeds on decaying organic matter, which includes dead plant material and decomposing leaves. While they primarily consume plant material, they can also ingest small amounts of animal matter, so they can be considered both herbivorous and occasionally carnivorous in their feeding habits. However, their diet mostly consists of decomposing plant material.
