Rollie pollies, also known as pill bugs or woodlice, are common terrestrial crustaceans often found in gardens and yards. They are harmless creatures, not insects, and are more closely related to shrimp and lobsters. These fascinating organisms are frequently sought for observation, educational purposes, or even as unique pets due to their distinctive ability to roll into a tight ball when disturbed.
Understanding Their Preferred Environment
Rollie pollies thrive in environments that offer consistent moisture, darkness, and abundant decaying organic material. This preference stems from their unique biology; unlike insects, they breathe through gill-like structures, which necessitate high humidity to function properly. Without sufficient moisture, they risk drying out.
They are detritivores, feeding on dead and decaying plant matter like leaves, wood, and other organic debris. This dietary need further influences their habitat choice, as moist, dark areas are rich in decomposing materials, providing food and humid conditions. They are most active at night, minimizing water loss by staying hidden during the day.
Common Hiding Places
Rollie pollies are found in many outdoor locations. They gather under objects providing shelter and moisture, such as rocks, logs, and discarded boards. Leaf litter and thick layers of garden mulch are also favored spots, offering humidity and a food source of decaying leaves.
Garden pots resting on soil create a dark, damp space underneath. Compost bins are another prime location, as they hold decomposing organic matter, a food source for rollie pollies. Loose bark on trees or fallen logs can also harbor these crustaceans. Occasionally, they might wander into damp basements or crawl spaces indoors, seeking moisture if outdoor conditions become too dry.
Effective Search Strategies
When searching for rollie pollies, carefully lift rocks, logs, or garden pots, as these are common daytime hiding spots. Observe the underside of these objects and the soil directly beneath them. Rollie pollies may initially roll into a ball when disturbed, but they will uncurl and begin to move after a short period.
The best times to search are after rain or during the evening and night, when humidity levels are higher. These conditions encourage rollie pollies to be more active and venture out from hiding places. Always return any lifted objects to their original position to protect their habitat and the other organisms living there.
