Stick insects, also known as phasmids, are masters of disguise and are found in Australia. They are harmless, peace-loving vegetarians that feed on leaves. While some species of these insects are fussy about the type of leaves they eat, most feed on gum and wattle tree foliage. They are known to eat the foliage of other backyard plants such as roses, Lilly-Pilly, and Guava.

What You'll Learn
Eucalyptus and Acacia leaves are common food sources
Australian stick insects, or phasmids, are a fascinating group of insects that feed on leaves. They are masters of disguise, often resembling the very leaves or sticks they feed on, and remain still during the day to avoid detection by predators. This makes them extremely difficult to spot in the wild.
Among the approximately 150 species of Australian stick insects, Eucalyptus (gum trees) and Acacia (wattles) leaves are common food sources. Many species of stick insects feed happily on these leaves, and they can often be found within the branches of these trees. In captivity, providing a small branch with fresh foliage in a vase or jar of water is an easy way to feed these insects.
However, it is important to note that some species of Australian stick insects are more specialised in their dietary requirements. For example, the Peppermint Stick Insect, Megacrania batesi, exclusively feeds on the leaves of the Screw pine (Pandanus tectorius). Additionally, the Spiny Leaf Insect, a popular species among enthusiasts, has been known to feed on eucalyptus leaves but can also be raised on rose and raspberry leaves in the absence of their usual food source.
To meet the dietary needs of Australian stick insects, it is recommended to provide a variety of leaves in their enclosure. This is because their food preferences can change over time, possibly due to seasonal variations in the chemical composition of the leaves. By offering a range of leaves, you can ensure that your stick insects get the nutrition they need and stay healthy.

Some species are picky eaters
Stick insects are vegetarians that feed on leaves. While some species are not fussy about the plants they feed on, others are very particular about the species of plants they eat. Most phasmids feed on either or both Eucalyptus (gum trees) and Acacia (wattle) foliage. However, some species are specialists, such as the Peppermint Stick Insect, which only eats the leaves of the Screw pine.
Some species of Australian stick insects have been observed to feed on the foliage of other backyard plants such as roses, Lilly-Pilly, and Guava. The Spiny Leaf Insect, for instance, is a species that feeds on eucalyptus leaves but has also been raised on rose and raspberry leaves by keepers outside of Australia, where eucalyptus is not always available.
It is important to note that stick insects rely on camouflage to protect themselves from predators, and they are very good at it. They remain still during the day and are most active at night when they feed. They eat entire leaves, making it tough to spot where they have been. This is why it is important to always be sure that your phasmids are actually eating what you are feeding them. Sometimes, they may be happy eating a particular species for a long time and then suddenly go off it. This may be due to seasonal changes in the chemicals within the leaves.
Stick insects get water from the leaves they eat, and they also get additional water from dew drops and rain on the plants they live on in the wild. In captivity, they need to be provided with water in the form of droplets on the leaves or by lightly misting the leaves, enclosure walls, and the insects themselves.

Stick insects also eat roses, raspberries, and guava
Stick insects are purely vegetarian. Most Australian stick insects, or phasmids, feed on either or both Eucalyptus (gum trees) and Acacia (wattles). However, some are specialists, such as the Peppermint Stick Insect, which only eats the leaves of the Screw Pine.
Young phasmids, or nymphs, hatch after one to three years and climb up towards soft green leaves. Once they reach the leaves of a food tree, they moult into a green or brown, slow-moving leaf mimic.
Some stick insects will take a range of other wild plants, with rose leaves being one option. Spiny Leaf Insects, for example, have been raised on rose leaves by keepers outside of Australia, where eucalyptus is not always available. Stick insects also eat raspberries, which are another option when eucalyptus is not available.
Some stick insects may also eat guava, a crop that is subject to attack by several kinds of insects. However, it is unclear whether Australian stick insects are among the insects that eat guava.

They get water from leaves and dew
Stick insects are fascinating creatures that are masters of disguise, resembling leaves or sticks and staying still during the day. They are harmless and peaceful vegetarians. In the wild, they feed on live plants, living on the branches and leaves they consume.
Stick insects get water from the leaves they eat, which is why it is important to provide them with fresh foliage. They also obtain additional water from dew drops and rain on the plants they inhabit.
In captivity, stick insects should be provided with a constant supply of fresh leaves. While some species are content with feeding on gum leaves, others require specific types of plants. It is important to offer them water daily to prevent dehydration, as the air inside houses tends to be drier than the outdoors. A simple way to do this is by lightly misting the leaves, enclosure walls, and the insects themselves.
Some species of stick insects have specific dietary preferences. For example, the Peppermint Stick Insect, Megacrania batesi, exclusively feeds on the leaves of the Screw pine, Pandanus tectorius. Similarly, the Spiny Leaf Insect, a popular species among enthusiasts, feeds on eucalyptus leaves but can also be raised on rose and raspberry leaves.

Young stick insects eat ant eggs
Young stick insects, also known as nymphs, have a unique start to their lives. After hatching from eggs, they resemble and behave like red-headed black ants. Ants play a crucial role in the early survival of these young stick insects. The eggs of stick insects have a knob called a capitulum, which attracts ants. Ants carry these eggs to their underground nests, consuming only the knob and leaving the rest of the egg protected in the nest.
Once the young stick insects hatch, they mimic the appearance and behaviour of ants. They climb upwards in search of soft green leaves, their first meal. This ant-like phase allows them to escape the nest and reach the leaves of food trees safely. It is a critical adaptation that ensures their survival in the vulnerable early stages of life.
The young stick insects then undergo moulting, shedding their exoskeletons and emerging with new ones. During this process, they hang upside down, remaining still and often not eating. Moulting typically occurs at night, and it is vital that the insects are not disturbed during this transformative period. After moulting, they may eat their old exoskeletons.
In captivity, young stick insects have specific dietary requirements. They require a constant supply of fresh leaves, preferably from live plants. While some species are content with feeding on gum leaves, others require specific plant species. It is important to provide a variety of leaves to determine which ones the insects prefer, as their preferences can change over time.
