Walking stick insects, also known as phasmids, are fascinating creatures known for their remarkable camouflage. Their bodies often mimic twigs or leaves, an adaptation that helps them blend seamlessly into their environment. This appearance can sometimes lead to the misconception that they are inanimate objects. However, these insects are alive and, like all animals, have specific dietary requirements. Understanding what pet walking stick insects eat is important for their well-being and helps ensure they thrive in captivity.
Natural Food Sources
In their natural habitats, walking stick insects are herbivores, primarily consuming leaves, as they are folivores. Many commonly consume leaves from plants such as oak, rose, hawthorn, and bramble. Other natural food sources include hazel, privet, and various fruit tree leaves, depending on the species and its native environment. Some Australian species, for instance, primarily feed on eucalyptus leaves.
Their diet in the wild depends on the vegetation available in their local ecosystem. Many species are observed eating readily available, non-toxic leaves. Bramble leaves are a common food source and remain green throughout the year, providing a consistent food supply. Stick insects typically avoid brightly colored leaves, which often indicate toxicity, favoring darker leaves instead.
Feeding Walking Sticks in Captivity
Providing appropriate food for pet walking stick insects involves offering fresh, clean, and pesticide-free leaves. Many popular pet species readily consume bramble, oak, and rose leaves. Other suitable options include privet, hawthorn, and hazel. Source leaves from areas free of chemical treatments, such as a personal garden or a known organic source, avoiding roadside plants contaminated by vehicle fumes.
To prepare the leaves, wash them thoroughly to remove any dust or debris. Present the leaves as fresh cuttings, ideally with stems placed in a jar of water to keep them hydrated for several days. Cover the jar’s opening to prevent insects from accidentally drowning. Regularly misting the leaves and enclosure daily provides essential hydration, as walking sticks drink water droplets from surfaces.
Unsuitable Food Sources
Avoid offering certain plant materials or substances to pet walking stick insects, as these can be harmful or fatal. Leaves treated with pesticides or herbicides are particularly dangerous and can lead to death. Even small amounts of these chemicals, which cannot be washed off, can be toxic. Therefore, never use leaves from garden centers or florists, as they are frequently chemically treated.
Some plants are inherently toxic and should never be offered. While specific toxic plants vary by species, common examples to avoid include ivy, rhododendron, and oleander. Although some species might tolerate small amounts of ivy, it is not recommended as a staple diet due to potential toxicity. Processed human foods are also unsuitable and lack the necessary nutrients for a stick insect’s specialized diet.
