Praying mantises are fascinating creatures that belong to the family of carnivorous insects known as mantids. With a unique ability to turn their heads 180 degrees, they are skilled hunters that depend on camouflage for survival. While they are found in various parts of the world, including Australia, this article will focus specifically on the diet of praying mantises in the Australian context. From their dietary preferences to the intriguing behaviour of female mantises consuming their male partners, the eating habits of these insects are both diverse and intriguing.

Praying mantises eat insects, insect eggs, mites, caterpillars, beetles, and aphids
Praying mantises are carnivorous insects that belong to the Mantidae family. They are predatory and use their powerful front legs to catch their prey. They are called 'praying' mantises because of the way they hold their front legs, which looks like they are praying. They have rows of sharp spines on their front legs that help them grip their prey.
The Garden Mantid is the most common praying mantid found in Sydney and is blue-green with a bright blue or purple spot on the inside of its front legs. It is carnivorous and feeds on small insects, including aphids.
Praying mantises lay their eggs in protective cases called ootheca, which can contain up to 200 eggs. The tiny hatchlings, called nymphs, emerge as worm-like larvae and moult their exoskeletons to become functional mantis nymphs. These nymphs are replicas of the adults but lack wings. They are predatory and will eat other nymphs or small insects like aphids or leafhoppers.
Praying mantises are beneficial to gardeners as they feed on insects that can be harmful to plants and crops.

They are beneficial to gardeners as they eat insects that harm plants and crops
Praying mantises are beneficial to gardeners as they feed on insects that harm plants and crops. They are carnivorous and prey on small insects, including aphids, mites, caterpillars, beetles, and insect eggs. Their appetite for these insects makes them an effective form of biological control for gardeners, helping to keep pest populations under control.
The praying mantis is a skilled hunter, using its powerful front legs with sharp spines to capture prey. It waits motionless, often well-camouflaged on a leaf or stem, before snapping up its prey with lightning speed. The praying mantis can turn its head 180 degrees, allowing it to detect even the slightest movement of potential prey. Its large compound eyes, with pseudo pupils, enable it to accurately judge distances for precise strikes.
Nymphs, or baby mantids, also contribute to pest control. They emerge as worm-like larvae and quickly moulting their exoskeletons to become functional mantis nymphs. These nymphs resemble miniature adults but lack wings. They feed on leafhoppers, aphids, and small flies, helping to control the populations of these insects.
Gardeners can encourage the presence of praying mantises by providing a suitable habitat and food sources. Praying mantises are found in warm to hot environments and rely on camouflage for survival. They can be attracted to gardens with plenty of green plants, bark, or wood where they can blend in and ambush their prey.
Additionally, gardeners can purchase praying mantis egg cases from garden centres or online stores. These egg cases should be placed on trees or shrubs in sunny locations to provide the warm conditions required for hatching. Releasing praying mantises or their egg cases into gardens can help create a natural balance, reducing the need for chemical pesticides.

They catch prey with their powerful front legs, which have rows of sharp spines
Praying mantises are predatory insects that catch their prey with their powerful front legs, which have rows of sharp spines. This method of catching prey is unique to the praying mantis. The name "praying" comes from the pose they hold their front legs in—as if they were praying. This pose is also where the name "mantis" comes from, as it means "prophet" in Greek.
The front legs of the praying mantis are equipped with sharp spines that act as grippers, allowing the insect to seize its prey with precision and force. The spines are arranged in rows, forming a powerful tool for capturing prey. This feature is essential for the mantis's survival, as it is a carnivorous creature that relies on catching prey to sustain itself.
The praying mantis's ability to capture prey is further enhanced by its large compound eyes, which are set well apart. This unique eye structure enables the mantis to accurately judge distances, improving its striking accuracy. The eyes also feature a noticeable dot, known as the pseudo pupil, which creates the optical illusion that the mantis is always looking at you. This adaptation may serve as a deterrent to potential predators.
The powerful front legs of the praying mantis are not just for catching prey. They also play a crucial role in the mantis's overall locomotion and navigation through its environment. The spines on the legs provide traction and stability, enabling the mantis to climb and maneuver with ease. This capability is especially advantageous when the mantis is hunting or evading its own predators.
In addition to their physical attributes, praying mantises exhibit strategic hunting behaviors. They often remain motionless, well-camouflaged on leaves or stems, waiting patiently for their prey to come within striking distance. This stealthy approach, combined with their powerful front legs, makes them formidable predators in their ecosystems.

The female praying mantis may eat the male during or after mating
The praying mantis gets its name from the way it holds its front legs, which appear similar to an animal praying. They are predatory insects that use their powerful front legs to catch their prey. They are found in warm to hot places on most continents of the world.
The propensity for cannibalism is largely dependent on the species, as captive-raised animals are generally well-fed. Even well-fed females can and do eat their mates. After a male and female connect, the life of the male becomes largely irrelevant, as his sexual organs will continue to live long enough to transfer a spermatophore. Being well-fed does reduce the chances of the female eating the male, but they have such large appetites that they will often try to eat something even when they are full.
To mitigate the occurrence of sexual cannibalism, steps can be taken such as having the female actively eat food while she is mating, putting a paper "collar" on her to prevent her from reaching behind to eat the male, and making sure the female is well-fed before attempting mating.

The praying mantis gets its name from the way it holds its front legs, as if in prayer
The praying mantis gets its name from the distinctive pose it adopts with its front legs, holding them together as if it is praying. This pose is often referred to as the 'folded praying position'. The front legs have rows of sharp spines, which the mantis uses to grip its prey.
The praying mantis is a member of the Mantidae family, which includes almost 75% of all praying mantid species in Australia. They are also known as mantids, and there are around 2000 different species worldwide. Mantids are found in warm to hot places across most continents.
The praying mantis is a predatory insect, and its diet consists of other insects, insect eggs, mites, caterpillars, beetles, and aphids. They are beneficial to gardeners as they feed on insects that can harm plants and crops. The hatchlings, or nymphs, of praying mantises have been known to eat other young mantises as their first meal.
Praying mantises are also known for the female's habit of eating the male during or after mating. The male's nutrients are valuable to the female in developing her eggs. The male's body continues the mating process instinctively, even if it has been partially dismembered.
The praying mantis has a triangular-shaped head with large eyes on each side, capable of detecting the slightest movement up to 35 metres away. It is the only insect that can turn its head 180 degrees. It also has excellent hearing, which helps it to detect the high-pitched sounds made by bats, one of its main predators.

Frequently asked questions
When they first hatch, praying mantis nymphs eat other nymphs that are hatching at the same time. As they get older, they eat leafhoppers, aphids, and small flies.
Adult praying mantises are carnivorous and feed on small insects, including mites, caterpillars, beetles, aphids, and insect eggs. They do not eat plants.
Praying mantises can be kept as pets, but they need a well-ventilated enclosure that is at least 40cm tall and made of mesh. They also need high humidity levels, which can be achieved by misting the enclosure daily.
No, but it is true for many species. The female eats the male's head and front legs, but he can continue mating for hours automatically. The nutrients from the male's body help the female develop her eggs.
