The Orchid Mantis: Breathtakingly Beautiful, Deceptively Deadly

By Olivia Barney

Imagine for a moment that you’re vacationing in the tropics. Everywhere you look, flowers are in full bloom. The bees are buzzing quietly. The sun is warming your skin. You are settling in for a much-deserved break. But little do you know, that amid these beautiful blossoms, tiny assassins are lying in wait — though not for you.

Blending in with the surrounding petals, the orchid mantis has the ability to stay perfectly still. But if a breeze picks up, it sways in sync with the flower. As soon as an unsuspecting pollinator meanders within striking distance, the orchid mantis makes its move. With lightning speed, the mantis uses its forelegs to grasp its prey. By the time the bee or butterfly realizes what has happened, it’s too late. They’re already lunch.

The Clever Beauty of the Orchid Mantis

There are more than 2,400 species praying mantises around the world. Many have the camouflaging browns and greens often seen here in Utah, but others showcase vibrant colors and unique body structures, making them appear comparatively alien.

The orchid mantis is one of those wondrous, alien-like beauties. Like other mantises, it features spiny, "raptorial" front legs that allow it to quickly and powerfully strike passing prey. But its unique hind legs have “femoral lobes,” extensions of the leg exoskeleton that resemble flower petals. This helps them hide in plain sight and makes them extremely successful predators. But there are other reasons that the orchid mantis is such a fearsome foe — including the implementation of two evolutionary tactics. The first is called active camouflage.

Active camouflage refers to an organism’s ability to change color to better blend into its surroundings. Think of an octopus blending into coral, or a flounder hiding among the sand. In this case, an orchid mantis can shift its color to various shades of white, pink, purple, and even a yellowish green. These shifts in color allow the mantis to both hide from predators and to effectively hide in ambush for prey. But unlike other animals, the orchid mantis can’t change color instantaneously. It takes days, or even weeks, to alter its hue, and it can only do so while it’s young and still growing. Still, implementing active camouflage allows the orchid mantis to match the environment it was born into, giving it a sort of superpower that other insects might not have.

The second evolutionary tactic that the orchid mantis uses is called “floral mimicry.” The orchid mantis mimics flowers to lure in potential prey using the combination of anatomical and behavioral adaptations — the expanded leg lobes that resemble flower petals and their ability to sway with the breeze just like a flower on a stalk.

Although these tactics are used by a variety of insects and other animals, the orchid mantis is particularly good at hiding in plain sight, and there’s no doubting its effectiveness. In fact, they’ve even been known to fool humans.

In 1879, an Australian journalist named James Hingsley was on a trip to Indonesia, when he seemingly saw an orchid devour an insect whole. He reported that he saw a flower “that catches and feeds upon live flies.” It wasn’t until nearly a century later, in 1972, that Guillaume-Antoine Olivier scientifically described and named the orchid mantis (though it had been observed and discussed by naturalists for many years in between).

Experience the Powerful Orchid Mantis for Yourself

Could an insect truly be this adept at hiding? Is the orchid mantis really as fearsome in the “bug world” as it sounds? Well, you can be the judge of that.

NHMU’s newest special exhibition, Bug World, allows you to fully immerse yourself in the world of insects. Built by the special effects masters behind Lord of the Rings and Avatar, the experience is unlike anything else you typically find at science museums. As you step inside this almost magical environment, you’ll feel as if you’ve been shrunk down to the size of the bugs you know and love.

It’s a perspective-altering experience that inspires greater appreciation for the innovation and incredible adaptations of bugs! In addition to interactive displays that test your reflexes, the exhibit also features four pod-like biomes, each focusing on a specific bug. The first pod you’ll encounter is dedicated to the orchid mantis, where you can watch it shift colors and catch prey — just don’t blink, or you might miss the moment it strikes!

Don't miss this one-of-a-kind experience! Bug World is only on display at NHMU through September 7, 2026. Entrance to this immersive experience is included with museum admission, which is always free for Museum Members. Prebook your tickets now and experience the wild world of bugs up close.
