Dive into a fascinating episode of "Stuff You Should Know" with Josh Clark and Chuck Bryant as they unravel the mysteries of the commonly misidentified garden dwellers known as roly-polies. These creatures are not the insects they are commonly mistaken for but are in fact, crustaceans who breathe through gills and have remarkably adapted to terrestrial life. Listen as Josh and Chuck explain the unique behaviors of these creatures, from how they roll into a ball to protect themselves to their uncommon dietary habits, and gain insight into the surprisingly complex life of these small beings.
In their exploration, Josh and Chuck also shed light on the ecological benefits that roly-polies confer upon our gardens and compost heaps, demonstrating that they are allies rather than foes in horticultural environments. Furthermore, get a sense of how these land crustaceans could play an instrumental role in pollution clean-up due to their ability to ingest and neutralize heavy metals. Join this episode of "Stuff You Should Know" for an enlightening look into the underestimated and often overlooked, the humble roly-poly.

Roly-polies, often mistaken for insects due to their small size and ubiquity in gardens, are actually crustaceans, a group that comprises crabs, lobsters, and shrimp. These creatures are particularly notable as the sole crustaceans that have fully adapted to land living. Interestingly, despite their terrestrial habitat, they continue to breathe through gills and thus require moist environments to facilitate their respiratory system.
When faced with threats, roly-polies engage in a defense behavior known as conglobation, which involves curling up into a tight ball. This not only protects them from predators but also helps to preserve moisture in their gills, which is vital for their survival, especially in drier climates.
Exhibiting a behavior termed self-coprophagy, roly-polies consume their own feces to recapture nutrients that were not absorbed during the initial digestion. Such a practice enhances their nutrient intake from what they consume.
Roly-polies contribute substantially to composting and are advantageous to gardens. Their dietary focus on decaying vegetation and carrion significantly aids in the decomposition process, thereby enriching the soil with nutrients and improving its fertility. Notably, they are not plant-threatening pests and do not carry diseases, reflecting their crucial role in maintaining a healthy soil ecosystem and reinforcing their status as helpers rather than harmful inhabitants of gardens.
In a display of their environmental utility, roly-polies have the astonishing capability of ingesting and crystallizing heavy metals within their bodies. This phenomenon could be harnessed to detoxify and reclaim polluted environments, positioning these creatures as potential agents in ecological cleanup and restoration efforts.
1-Page Summary
Despite their small size and common presence in gardens, roly-polies are not insects. They are, in fact, crustaceans—a group that includes crabs, lobsters, and shrimp. Originally from the Mediterranean, these unique creatures have successfully spread across the globe.
Roly-polies are unique in the crustacean family; they are the only members that have adapted to a terrestrial lifestyle. Their adaptation is a significant evolutionary step, distinguishing them from their aquatic relatives.

Roly-polies, also known as pill bugs, woodlice, or armadillo bugs, play an essential role in the gardening and composting process due to their feeding habits and non-destructive nature.
One of the primary reasons roly-polies are beneficial for gardens is their diet consisting mainly of decaying plant matter and dead animals. This dietary preference enables them to significantly contribute to the decomposition process in compost piles and garden soil. As they feed on organic material, roly-polies help break it down into smaller pieces, which speeds up the decomposition process and enhances soil fertility. This natural cycle ensures that valuable nutrients return to the soil, promoting plant health and vigor.
Another advantage of having roly-polies in the garden is that they generally do not harm living plants nor do they transmit diseases. U ...
