Australia is home to around 150 species of phasmids, also known as stick insects, which are native to gum trees but can also be found in gardens on rose bushes or fruit trees. Phasmids are herbivores, meaning they eat plants, and most feed on the leaves of eucalyptus and acacia trees. However, some phasmids are specialists and will only eat one type of plant.

Eucalyptus leaves are eaten by all phasmid species commonly kept at home or in classrooms
Phasmids are relatively easy to care for and can be housed in small aquariums placed on their side with a door constructed of plywood, plastic, or metal. These insects are most commonly found in gum trees but can also be spotted in gardens on rose bushes or fruit trees. While some phasmid species are very particular about the type of plant they consume, eucalyptus leaves are a safe option for those commonly kept in captivity.
Eucalyptus, or gum trees, are a favourite food source for many phasmid species. In the wild, phasmids typically live in the branches of gum trees, making eucalyptus leaves a natural part of their diet. This preference for eucalyptus may be due to the leaves' high nutritional value or the trees' abundance in certain regions. Additionally, the strong scent of eucalyptus may play a role in attracting phasmids to these trees.
While eucalyptus leaves are a staple food for captive phasmids, it is important to note that these insects can also feed on other plant species. In their natural habitat, phasmids may consume leaves from a variety of trees and shrubs, including acacia (wattles), lilly pilly, and guava. Some phasmids have even been known to eat the foliage of backyard plants such as roses, raspberries, and blackberries.
Providing a varied diet for captive phasmids is essential to ensure they receive adequate nutrition. While eucalyptus leaves may be their primary food source, offering occasional alternatives such as rose or raspberry leaves can enhance their diet and provide additional nutrients. It is also crucial to ensure that the phasmids are actually consuming the food provided, as their survival instincts and camouflage abilities can sometimes make it difficult to gauge their eating habits.

Some phasmids are specialists and will only eat one type of plant
Phasmids are herbivores, which means they eat plants. They are also known as stick insects, owing to their resemblance to sticks or leaves. There are around 150 species of phasmids in Australia, out of over 3000 species worldwide.
Most phasmids eat leaves from a variety of plants, including eucalyptus and acacia trees. However, some phasmids are specialists and are very fussy about the species of plants they feed on. For example, the Peppermint Stick Insect, Megacrania batesi, is a specialist that only eats the leaves of the Screw Pine, Pandanus tectorius. It gets its name from the peppermint-like secretion it produces when alarmed.
Some phasmids are even more selective and will only eat one type of plant. For instance, the Spiny Leaf Insect, Extatosoma tiaratum, also known as Macleay's Spectre Stick Insect, is a popular pet in Australia and overseas. While they eat eucalyptus leaves in their natural habitat, they have also been raised on rose and raspberry leaves by overseas keepers.
Other phasmids may also eat the foliage of backyard plants such as roses, Lilly-Pilly, and Guava. Phasmids are an important part of the forest ecosystem, as they consume early successional plants and enrich the soil through defecation, enabling late succession plants to become established and encouraging the recycling of the tropical forest.

Mulberry, rose, oak, and blackberry leaves are also eaten by some phasmids
Phasmids, also known as stick or leaf insects, are herbivores that feed mostly on the leaves of trees and shrubs. Mulberry, rose, oak, and blackberry leaves are also eaten by some phasmids. In fact, some phasmids are very fussy and will only eat one type of plant. For example, the Peppermint Stick Insect, Megacrania batesi, only eats the leaves of the Screw Pine, Pandanus tectorius.
Spiny Leaf Insects, Extatosoma tiaratum, also called Macleay's Spectre Stick Insect, eat eucalyptus leaves but have also been raised on rose and raspberry leaves by keepers overseas where eucalyptus is not always available. Mulberry leaves are also a favourite of some Australian prickly stick insects.
Phasmids are found on all continents except Antarctica, but they are most abundant in the tropics and subtropics. They are usually green or brown but may reveal brightly coloured underwings when they fly. They have developed many unusual shapes to camouflage themselves to avoid detection by predators.
In Australia, phasmids are sometimes found in gardens on rose bushes or fruit trees. They are also found in gum trees, but because of their excellent camouflage, they are often overlooked.

Lilly-Pilly and Guava are examples of backyard plants phasmids will eat
Phasmids, also known as leaf or stick insects, are insects that eat leaves and resemble leaves or sticks. They are usually green or brown but may reveal brightly coloured underwings when they fly. Australia is home to around 150 species of phasmids.
Most phasmids feed on either or both Eucalyptus (gum trees) and Acacia (wattles). Lilly-Pilly is one of Australia's most popular native plants, encompassing a vast group of evergreen rainforest species. In Australia alone, you'll find over fifty species of Lilly Pillies, which are also known as "brush cherries", "satinash", and Riberry (Syzygium luehmannii). This group of flowering plants belong to the Syzygium genus, covering around 1200 flowering plants belonging to the Myrtle family. Lilly Pilly is therefore a common plant that phasmids will eat.
Some phasmids are very fussy and will only eat one type of plant. For example, the Peppermint Stick Insect, Megacrania batesi, only eats the leaves of the Screw Pine, Pandanus tectorius.
Guava is an evergreen edible hedging plant with aromatic foliage and delicious fruit. The Strawberry Guava tree produces large white flowers in autumn that turn red to purple when the fruit is ready for harvest. The Strawberry Guava is a member of the Psidium genus. While it is not clear whether phasmids will eat the leaves of the Strawberry Guava tree, it is likely that they will, given that phasmids are known to eat leaves from a variety of plants.

Phasmids are herbivores and eat the entire leaf blade
Phasmids, also known as stick insects, are herbivores that feed on leaves. They are insects that resemble leaves or sticks, with most species being quite rare. They are found on all continents except Antarctica and are most abundant in the tropics and subtropics. In Australia, there are around 150 species of phasmids, with some examples being spiny leaf insects, strong stick insects, goliath stick insects and spur-legged leaf insects.
Phasmids feed on a variety of leaves, including those from eucalyptus (gum trees) and acacia (wattles) trees. Some species are very particular about the type of leaves they consume, with the Peppermint Stick Insect, for instance, exclusively eating the leaves of the Screw Pine. Other species of phasmids are known to eat the leaves of rose bushes, raspberry bushes, mulberry, oak, ivy, blackberry, lilly pilly and guava.
Phasmids play an important role in the forest ecosystem, as they contribute to maintaining succession and resilience in climax forests. They do so by consuming early successional plants and enriching the soil through defecation, which helps late succession plants become established.
Phasmid nymphs, or young phasmids, also consume leaves. After hatching, they climb rapidly upwards in search of soft green leaves to feed on. Phasmids are known to eat the entire leaf blade, and in the event of heavy outbreaks, they can completely defoliate trees, leading to their death.
