What Do Rolly Pollies Eat

Explore the fascinating diet of rolly pollies, from scavenging on decaying organic matter to consuming fungi and algae. Learn about their role in nutrient cycling and ecological processes.


Rolly pollies, also known as pill bugs or woodlice, are fascinating creatures that are often found in gardens, under rocks, and in damp environments. But have you ever wondered what these small critters eat? In this article, we will explore the diet of rolly pollies and provide insights into their feeding habits.

What do Rolly Pollies Eat?

Rolly pollies are scavengers and feed on decaying organic matter like leaves, plants, and wood. They play a crucial role in breaking down dead plant material and returning nutrients to the soil. Rolly pollies also consume fungi, algae, and even small insects.

Examples of Rolly Pollie Diets

  • Feeding on fallen leaves in a garden
  • Consuming rotting wood in a forest
  • Scavenging on decaying plant matter in a compost pile

Case Studies

A study conducted in a forest ecosystem found that rolly pollies are important decomposers, aiding in the decomposition process of leaf litter. Without these small creatures, the nutrient cycling in the ecosystem would be disrupted, impacting the overall health of the environment.

Statistics on Rolly Pollie Diets

Research has shown that rolly pollies consume approximately 30% of leaf litter in certain ecosystems, highlighting their importance in recycling nutrients and maintaining soil health. These statistics emphasize the significant role that rolly pollies play in ecological processes.


Rolly pollies may seem like insignificant creatures, but they play a vital role in the ecosystem by consuming decaying organic matter and recycling nutrients back into the soil. Understanding their diet and feeding habits can help us appreciate the importance of these small critters in maintaining ecological balance.
