What Is a Praying Mantis? Facts, Benefits and Environmental Role 

Some people believe that spotting a praying mantis can sprinkle a little good luck into their lives. Others, however, might see those head-spinning, exorcist-like abilities (they can turn their heads a full 180 degrees!) as a reason to steer clear. 

Regardless of your beliefs about these long-legged wonders, there’s no denying that praying mantises are incredibly beneficial to the environment. So, if you happen to cross paths with one, why not tip your hat to the little guy before continuing on your way? 

Still on the fence? We’re here to unveil all the fantastic ways praying mantises contribute to our world.

What Is a Praying Mantis? 

When you look into the large compound eyes of a praying mantis, you might feel as if it’s peering deep into your soul. Its triangular head, spindly front legs and long body only enhance its unique, otherworldly aesthetic. But rest assured — a praying mantis is, in fact, an insect. 

Physical Characteristics 

Just like bees, butterflies and ants, praying mantises have a segmented body divided into the head, thorax and abdomen. With four legs positioned at the abdomen and two arm-like forelegs closer to their heads, these five-inch creatures are both fascinating and functional. 

Scientific Classification and Origin 

Known scientifically as Mantis religiosa, this species of praying mantid hails from Europe, parts of Asia and Africa. It made its way to North America over a hundred years ago

Where Do Praying Mantises Live? 

Praying mantises prefer warm habitats full of grass, shrubs and other forms of greenery. These lush environments offer the perfect buffet for their carnivorous appetites — other insects, spiders, frogs, lizards and even the occasional hummingbird. 

What Are the Benefits of Praying Mantises? 

While praying mantises are not native to North America and are considered invasive, they’ve managed to become valuable contributors to their adopted home, offering a range of benefits to ecosystems and humans alike. Let’s explore some of the beneficial ways praying mantises impact the world around us. 

Natural Pest Control in Gardens and Farms 

If you were to step into your backyard right now, you’d likely spot a handful of pests that you’d rather not share your space with — mosquitoes and cockroaches included. But pesticides often contain harmful substances that can contribute to pollution, reduce biodiversity and negatively impact the health of people and animals. 

Fortunately, praying mantises are nature’s pest control experts, and they’re more than happy to help you manage these unwanted guests. If you have a garden or are looking for a way to rid crops of unwanted pests, consider using praying mantises as a natural form of pest control. As carnivorous predators, mantises feast on a wide variety of insects, making them an ally in keeping your yard bug-free. 

In addition to mosquitoes and cockroaches, mantises also target other notable pests that can wreak havoc on plants and gardens, like: 

  • Aphids 
  • Grasshoppers 
  • Caterpillars 

A juvenile mantis’ appetite for aphids is a major advantage, as these tiny sap-sucking insects can quickly decimate crops and ornamental plants. Grasshoppers and caterpillars, notorious for chewing through leaves and damaging greenery, are no match for a hungry adult mantis either. 

Food Source 

While praying mantises are fierce predators, they’re far from invincible. In fact, they play a critical role in the food chain, serving as both hunter and hunted. Their ability to control pest populations makes them valuable contributors to the ecosystem. 

But mantises, too, find themselves on the menu for larger animals. Birds, frogs, bats and even some larger spiders see these stealthy insects as a worthwhile meal. 

This dynamic keeps the ecosystem in balance, ensuring that mantises don’t overrun their habitats while providing a vital food source for their predators. So, while mantises may seem like the apex predators of the insect world, they’re just one piece of the intricate web that keeps nature balanced. 

Frequently Asked Questions About Praying Mantises 

Praying mantises have captured our attention for centuries, inspiring everything from folklore to scientific study. Below are some common questions people ask about mantises: 

  • What is a mantis vs. a praying mantis? 
    “Mantis” is a general term used for species within the family Mantidae, which includes hundreds of different mantids. The “praying mantis” specifically refers to species whose folded forelegs resemble a prayer posture. One of the most well-known is Mantis religiosa, often simply called the European mantis. 
  • Are praying mantises good luck? 
    In many cultures, spotting a praying mantis is thought to symbolize peace, focus or even good fortune. While science can’t confirm luck, their presence in your garden is a good sign that your plants may benefit from their natural pest control abilities. 
  • Do praying mantises bite humans? 
    Praying mantises are not dangerous to people. They may nip if handled roughly, but they don’t carry venom or pose any health risks. In fact, most mantises avoid human contact and prefer to stick to hunting smaller prey. 
  • How do praying mantises help the environment? 
    Mantises play a dual role in ecosystems: They reduce pest populations by feeding on insects like aphids, flies and caterpillars while also serving as a food source for birds, frogs and bats. This balance makes them an important contributor to healthy ecosystems. 
  • Is it safe to keep a praying mantis in the garden? 
    Yes — in fact, it’s encouraged. Praying mantises help protect plants by keeping harmful insects in check. You can attract them naturally by planting native flowers, providing water or even releasing egg cases. Just remember that mantises are generalist predators, so they won’t discriminate between “bad” pests and beneficial insects like bees. 

How to Attract (and Keep) Praying Mantises in Your Garden 

To create a welcoming environment for praying mantises in your garden, try these tips: 

  • Plant native flowers  
    Wondering what to feed a praying mantis? If they’re living freely in your garden, providing a delectable diet is easy. Opt to add a few shrubs, flowers and tall grasses that naturally attract food sources for mantises. 
  • Create a water source  
    Whether it’s a shallow dish of water or a small birdbath, mantises need access to water to thrive. Providing a consistent water source will encourage them to stay in your garden. 
  • Release egg cases  
    Praying mantises lay large egg cases, called oothecae, where their eggs develop before hatching. If you’re not seeing mantises in your garden despite your best efforts, consider purchasing an ootheca from a garden supply store. 

    Place it in your garden, and once the nymphs hatch, they’ll begin feasting on smaller pests. As they grow, they’ll move on to larger, more troublesome insects.
