Rolly pollies, also widely known as pill bugs or woodlice, are common terrestrial crustaceans found in many environments. They are not insects, but are more closely related to marine animals like shrimp and crabs. Observing these fascinating creatures can offer a glimpse into the hidden world of decomposers and their important role in ecosystems. Their presence often indicates a healthy, balanced habitat where organic matter is actively breaking down.
Preferred Habitats and Environments
Rolly pollies thrive in locations that provide specific environmental conditions, primarily damp, dark, and sheltered spaces. Their biological makeup, as crustaceans, means they possess gill-like structures for respiration that necessitate a consistently moist environment to function effectively. Without sufficient humidity, these structures cannot properly absorb oxygen, leading to desiccation.
These small arthropods frequently establish themselves under various forms of ground cover. Common outdoor spots include beneath rocks, logs, bricks, garden pots, leaf litter, compost piles, and layers of mulch. Decaying organic material in these areas provides both food and moisture. Decaying wood or bark also offers suitable haven, retaining moisture and providing crevices.
In gardens, they are often found in damp soil, particularly in shaded beds or near building foundations where moisture accumulates. Rolly pollies are more active at night, remaining in moist spots during the day. Activity increases after rain or during high humidity.
Tips for Locating Rolly Pollies
Discovering rolly pollies requires a gentle and methodical approach to avoid disturbing their delicate habitats. When searching under objects like rocks or logs, carefully lift them to reveal the hidden space beneath. This allows for observation without causing undue stress to the creatures or their immediate surroundings. Remember that these small crustaceans are fragile.
Using a small trowel or a sturdy stick can be beneficial for gently sifting through loose soil, leaf litter, or mulch. This method helps uncover rolly pollies without direct handling. Patience is helpful when searching; take time to look closely into dark, moist crevices where they might be resting or foraging. Observing quietly for a moment after lifting an object can often reveal their movement as they react to the sudden light.
Observing Rolly Pollies Safely
Once you have located rolly pollies, observing them responsibly ensures their well-being and a positive experience. It is best to minimize direct handling, as their bodies are delicate and prone to injury. If handling is necessary, use extremely gentle hands, supporting their entire body. After a brief observation, return them promptly to their original habitat.
Observing them in their natural setting is ideal, but for a closer look, you might briefly place one in a clear container with some material from its habitat. This allows for detailed inspection before releasing it back to its habitat. After your observation, it is important to return any lifted rocks, logs, or other objects to their exact original positions. This helps maintain the microhabitat structure and ensures that other organisms sharing the space are not unduly impacted.
