Rollie pollies, also known as pill bugs or woodlice, are common invertebrates found in gardens and damp environments. They are terrestrial crustaceans, more closely related to crabs and lobsters than to insects. Rollie pollies are detritivores, meaning they consume decaying organic matter. This positions them as natural recyclers, playing a significant role in their habitats. Understanding their diet provides insight into their ecological contributions and how to care for them in captivity.
Natural Diet of Rollie Pollies
In their natural environments, rollie pollies primarily consume decomposing organic material. Their diet includes rotting wood, fallen leaves, and other dead plant matter, which provides them with essential nutrients. They possess specialized mouthparts that enable them to scrape and chew these decaying substances. This consumption of decaying matter helps them break down organic debris and return valuable nutrients to the soil, contributing to nutrient cycling.
Their diet also extends to other organic sources found in their damp habitats. Rollie pollies consume fungi, dead insects, and occasionally animal feces. This varied diet highlights their adaptability. While they primarily prefer dead material, if other food sources are scarce, they may sometimes nibble on tender plant parts or ripe fruits in contact with the soil.
Feeding Rollie Pollies in Captivity
Providing a suitable diet for rollie pollies in a captive environment involves mimicking their natural food sources while ensuring variety and nutritional balance. Fresh vegetables are a suitable option, including thinly sliced carrots, cucumber, zucchini, and potatoes. Leafy greens like lettuce can also be offered, though they provide less nutritional value compared to other vegetables. These items should be organic and thoroughly rinsed to remove any potential pesticide residues.
Fruits can be given in moderation, with options such as apple and pear being suitable. Excess moisture and sugar from fruits can lead to mold growth, so uneaten portions should be removed promptly. To supplement their diet with protein, small amounts of fish flakes or pet food can be provided. Calcium sources are also important for their exoskeleton health, such as crushed eggshells or cuttlebone.
Foods to Avoid
Certain foods and substances can be harmful to rollie pollies and should never be offered. Processed foods, sugary items, and anything containing artificial preservatives or colors should be avoided due to their chemical composition. Citrus fruits, such as lemons, limes, and oranges, are also detrimental because their high acidity can disrupt the digestive systems of rollie pollies.
Any food that has been treated with pesticides or other chemicals poses a serious risk and must be avoided. Moldy food should also be removed immediately, as it can harbor harmful bacteria and fungi. Avoid nightshade vegetables like tomatoes, eggplants, and certain potatoes, as they may contain compounds toxic to isopods. Pine products, copper, and members of the onion family like garlic and chives are also recognized as harmful due to their inherent properties or toxicity.
