Some bugs look like bright flowers.
They hide on green leaves. This helps them stay safe. It also helps them find food. They wait for a snack to come near. Can you see the bug?
Some bugs look like bright flowers.
One kind is the orchid mantis. It lives in a rainforest. It is often white with pink marks.
This bug stays very still. It waits on a plant. Small flies fly near it. They think it is a flower. Then the mantis eats the fly.
Young bugs can bend their bodies. This makes them look even more like flowers. The big adults cannot bend as much.
Some bugs use smells too. They release a scent to trick bees. This helps them find food.
Many people like to keep these bugs as pets.
Some insects look just like bright flowers. This is called aggressive mimicry. That is a way to trick other bugs. These mantises use colors to hide from predators. They also use colors to catch food.
The orchid mantis lives in Southeast Asia. It is often white with pink marks. It can even absorb UV light. This is light that humans cannot see. To a bee, the mantis looks like a blue flower. This helps it attract pollinators.
Young orchid mantises use a special trick. They make a scent with chemicals. This scent mimics the smell of a bee. It helps them catch oriental bumblebees. They store these chemicals in their mandibles. Mandibles are the mouth parts of the insect. They let the scent out when they hunt.
Adult mantises are different. Their wings are too large to bend. Young mantises can bend their bodies upward. This makes them look like a flower. Many people like to keep these mantises as pets.
Flower mantises are amazing insects that use a trick called aggressive mimicry. This means they look like something else to get what they want. They use this to hide from predators that might eat them. They also use it to lure in tasty prey. These insects have special colors and behaviors to match flowers. This helps them blend into the plants around them.
Many flower mantises work by waiting very still on plants. They might sit on leaves or inside bright flowers. The orchid mantis is a great example of this. It has a white body with pink markings. It does not mimic just one specific flower. Instead, it uses colors that work in its habitat. This helps it catch many different types of insects.
One way they work is by using light. The orchid mantis can absorb UV light just like a flower. Many insects can see this special light. To these insects, the mantis looks blue. This stands out against the red leaves in the background. This makes the mantis look like a beautiful flower. It is a very clever way to hunt.
Young orchid mantises use even more tricks to hunt. They use something called aggressive chemical mimicry. They release chemicals called 3HOA and 10HDA from their mandibles. These chemicals smell like the pheromones of a bee. This trick helps them attract the oriental bumblebee. Adult mantises do not make these specific chemicals. The young ones use them to catch their food.
History shows us how these insects behave in the wild. In 1940, Hugh Cott wrote about these amazing creatures. He used accounts from Nelson Annandale to describe them. They found that mantises hunt on the Straits Rhododendron. This plant is also called Melastoma polyanthum. The young mantises act like a decoy to trick flies. They even sway from side to side to look real.
Flower mantises are a group of insects that use a clever survival strategy called aggressive mimicry. This technique allows them to look and act like something else to achieve their goals. They use these disguises to attract prey and to hide from predators. By mimicking the colors and behaviors of flowers, they blend into their natural habitats. Most known species of these mantises belong to the family Hymenopodidae. They are a diurnal group, meaning they are active during the daylight hours.
The mechanism of their mimicry involves both visual and chemical deception. Visually, many species use specific colorations to match the foliage and flowers around them. For example, the orchid mantis, known scientifically as Hymenopus coronatus, has a body that is often white with pink markings. This insect can even absorb ultraviolet (UV) light in the same way that real flowers do. Because many pollinators are sensitive to UV light, the mantis appears blue to them. This blue color contrasts against the red appearance of the background foliage.
Chemical mimicry is another layer of deception used by certain life stages. Juvenile orchid mantises perform aggressive chemical mimicry to lure their preferred prey. They secrete a mixture of two specific chemicals: 3HOA and 10HDA. These chemicals are stored in their mandibles, which are the mouthparts used for biting. When hunting, the juveniles release these substances to imitate the pheromones of the oriental bumblebee. This chemical trick specifically attracts the bees, but adult mantises do not produce these chemicals.
The physical appearance of these insects changes as they grow through different life stages. This is known as a morphological dichotomy. In the case of the orchid mantis, the juveniles can bend their abdomens upward. This movement allows them to look much more like a flower. However, once they become adults, their wings grow too large for this behavior. This change suggests that adults must rely on other processes to attract their prey.
Historical accounts have helped scientists understand how these mantises hunt in the wild. In his 1940 book, *Adaptive Coloration in Animals*, Hugh Cott shared observations from Nelson Annandale. Annandale described the orchid mantis hunting on the flowers of the Straits Rhododendron, or *Melastoma polyanthum*. He noted that the nymph acts as a decoy through its special alluring coloration. The mantis will climb up plant twigs and stand still to imitate a flower. It may also sway from side to side to appear more realistic to passing insects.
There is a wide variety of flower mantis species found across different parts of the world. The orchid mantis is native to Southeast Asia. In contrast, the Egyptian flower mantis, or *Blepharopsis mendica*, is found in North Africa and the Canary Islands. The *Idolomantis diabolica*, known as the giant devil's flower mantis, lives in Central and East Africa. These large insects can reach up to 13 cm in length. Other species, like the *Creobroter gemmatus*, are found in South and Southeast Asia.
These insects are often studied for their unique defensive behaviors, such as deimatic displays. A deimatic display is a sudden movement or color flash used to startle a predator. For example, the *Pseudocreobotra wahlbergii* can flash bright hindwings to scare away threats. The *Blepharopsis mendica* can rotate its head and thorax to one side during such a display. Many of these species are also popular among people who keep insects as pets. Their complex lives show how closely animals are connected to the plants in their ecosystems.
