The Short Answer: What Exactly Is a Praying Mantis?

Let's define our subject clearly: a praying mantis is an insect belonging to the order Mantodea, characterized by elongated bodies, triangular heads with large compound eyes, and specialized front legs modified for grasping prey.

Key identifying features include:

Triangular head: Can rotate 180 degrees—the only insect capable of looking directly over its shoulder
Large compound eyes: Provide exceptional depth perception for judging strike distances
Raptorial forelegs: Front legs modified into grasping tools lined with sharp spines
Elongated body: Streamlined shape that aids camouflage among vegetation
Camouflage abilities: Can resemble leaves, sticks, flowers, or grass depending on species
Ambush hunting strategy: Remains motionless, then strikes with lightning speed

There are approximately 2,400 known species of mantises worldwide, distributed across every continent except Antarctica . They range in size from the tiny Australian Bolbe pygmaea at just 1 cm (0.4 inches) to the massive Hierodula membranacea reaching 15-20 cm (6-8 inches) .

The Name: Why "Praying" Mantis?

The name "praying mantis" comes from the characteristic posture of their front legs.

Origin of the Name
When at rest, mantises hold their raptorial forelegs folded together in front of their faces. This posture resembles hands clasped in prayer, leading to the common name "praying mantis." The term dates back to ancient Greece, where the mantis was considered a prophet or seer due to this contemplative pose.

Cultural Significance
Across cultures, mantises have been viewed as:

Ancient Greece: Considered prophets with supernatural powers
African traditions: Often seen as gods or messengers
Chinese culture: Valued for their fighting spirit, inspiring martial arts movements
European folklore: Sometimes associated with witchcraft and divination
Modern times: Appreciated as beneficial garden predators and fascinating pets

The "Preying" Mantis Connection
Some sources spell it "preying mantis" to emphasize their predatory nature. Both spellings are technically correct—"praying" for the posture, "preying" for the behavior.

Taxonomy and Classification: Where Mantises Fit in the Animal Kingdom

Understanding mantis classification helps place them in context with other insects.

Scientific Classification

Kingdom: Animalia (animals)
Phylum: Arthropoda (arthropods)
Class: Insecta (insects)
Order: Mantodea (mantises)
Family: 15+ families including Mantidae, Hymenopodidae, and others
Genera: Approximately 430 genera
Species: Approximately 2,400 known species

Closest Relatives
Mantises are most closely related to:

Cockroaches (Blattodea): Share a common ancestor; mantises evolved from cockroach-like insects
Termites (Isoptera): Also closely related, though mantises are solitary while termites are social
Stick insects (Phasmatodea): Distant relatives with similar camouflage strategies

Evolutionary History
Mantises have an ancient lineage:

Origin: First appeared approximately 400 million years ago during the Carboniferous period
Fossil record: Well-preserved in amber, showing little change over millions of years
Diversification: Spread across continents, adapting to local conditions while maintaining basic body plan
Modern distribution: Found on every continent except Antarctica

Physical Characteristics: Built for Predation

Every aspect of mantis anatomy is optimized for their role as ambush predators.

The Head: A Predator's Control Center

A mantis's head is its most distinctive feature:

Triangular shape: Allows wide field of vision while remaining camouflaged
Rotational ability: Can turn 180 degrees—the only insect that can look directly behind itself
Compound eyes: Large and widely spaced, providing excellent depth perception and binocular vision
Simple eyes (ocelli): Three small eyes between compound eyes for detecting light levels
Antennae: Used for smell and touch, longer in males for detecting female pheromones
Mouthparts: Powerful mandibles for tearing and crushing prey

The Eyes: Nature's Most Complex Visual System

Mantis eyes deserve special attention:

12-16 photoreceptor types: Humans have only 3 (red, green, blue)
Ultraviolet detection: Can see wavelengths invisible to humans
Infrared detection: Some species can detect heat signatures
Polarized light detection: Can see light polarization patterns
Circularly polarized light: Some species detect this unique visual information
Pseudopupil: The dark spot that seems to follow you is an optical illusion caused by light absorption

This visual system allows mantises to judge strike distances with incredible precision and detect prey that would be invisible to other predators.

The Raptorial Forelegs: Nature's Bear Traps

The front legs are the mantis's primary weapons:

Coxa: Elongated first segment that extends the leg's reach
Trochanter: Small joint connecting coxa to femur
Femur: Thick, muscular segment lined with sharp spines
Tibia: Opposing segment with interlocking spines
Tarsus: Clawed foot for walking and gripping
Strike speed: 50-70 milliseconds—faster than human reaction time
Grip strength: Spines interlock, creating inescapable cage

The Thorax: Powerhouse and Support

Prothorax: Elongated first segment supporting head and front legs; provides extra reach
Meso- and metathorax: Support middle and hind legs and wings (if present)
Legs: Four walking legs for movement and stability
Wings (in adults): Two pairs—thick forewings (tegmina) protect delicate hindwings

The Abdomen: Digestion and Reproduction

Segmented structure: 10 segments containing digestive and reproductive organs
Sexual dimorphism: Females have broader abdomens for egg production; males are slimmer
Cerci: Paired appendages at tip for sensory functions
Spiracles: Breathing pores along sides

Types of Praying Mantises: A World of Diversity

The mantis order Mantodea contains incredible variety. Here are some notable types:

Behavior and Lifestyle: How Mantises Live

Understanding mantis behavior reveals what makes them unique.

Hunting Strategy

Mantises are ambush predators. Their hunting sequence is:

Selection: Choose a location with good camouflage and prey traffic
Waiting: Remain motionless for hours or days
Detection: Spot prey with excellent vision
Tracking: Turn head to follow prey movement
Strike: Explosive forward movement of raptorial legs
Capture: Trap prey between spiny forelegs
Consumption: Begin eating immediately, typically starting with head

Diet

Mantises are carnivorous and eat:

Insects: Crickets, grasshoppers, flies, moths, butterflies, bees, wasps, beetles
Arachnids: Spiders of various sizes
Other mantises: Cannibalism is common
Small vertebrates (large species): Hummingbirds, small lizards, small frogs, small fish (rare)

Activity Patterns

Diurnal: Most species are active during daylight hours
Nocturnal: Some species, especially males, fly at night
Crepuscular: Active at dawn and dusk in some species
Temperature dependent: Activity increases with warmth

Defensive Behaviors

When threatened, mantises have a graded response:

Camouflage: Freeze and rely on appearance to avoid detection
Slow retreat: Gradually move away from threat
Threat display: Rear back, spread forelegs, open wings, hiss
Strike: Defensive strike if physically contacted
Flight: Fly away (in winged species)

Flight

Not all mantises fly
Males are generally better fliers than females
Flight is primarily for finding mates, not hunting
Most flight occurs at night

The Mantis Life Cycle: From Egg to Adult

Mantises undergo simple metamorphosis with three life stages.

Stage 1: Egg (Ootheca)

Females produce foam-like egg case called ootheca
Ootheca hardens into protective nursery
Contains 10-400 eggs depending on species
Overwinters in temperate regions, hatching in spring

Stage 2: Nymph

Hatch as tiny versions of adults without wings
Go through 5-10 molts (instars) as they grow
Each molt increases size and develops wing buds
Cannot fly until adulthood
High mortality rate from predators and cannibalism

Stage 3: Adult

After final molt, fully winged (in flying species)
Reproduction is sole focus
Adults live 3-6 months typically
Die with first frost in temperate regions

Lifespan

Total lifespan: 10-12 months average
Nymph stage: 4-6 months
Adult stage: 3-6 months
Captivity: Up to 18 months with optimal care
Females live longer than males

Mating and Reproduction: The Famous Cannibalism

Mantis reproduction is infamous for sexual cannibalism.

Courtship and Mating

Female releases pheromones when ready to mate
Male detects pheromones and approaches carefully
Male may perform courtship display to signal he's prey, not predator
Male mounts female and mates
Mating can last hours

Sexual Cannibalism

Female may eat male during or after mating
Occurs in about 13-28% of wild matings
More common in captivity due to stress
More likely when female is hungry
Provides nutrition for egg production
Males sometimes continue mating even after decapitation

Ootheca Production

After mating, female produces ootheca
Attaches to branch, stem, fence, or building
May produce multiple oothecae over several weeks
Dies when winter arrives, life cycle complete

Mantises in Gardens and Agriculture

Mantises play important roles in human-managed environments.

Beneficial Aspects

Natural pest control: Eat aphids, caterpillars, grasshoppers, beetles
Reduce need for chemical pesticides
Fascinating to observe, encouraging garden engagement
Educational opportunities for children and adults

Potential Drawbacks

Non-discriminating predators: Also eat beneficial insects (bees, butterflies, other predators)
Not a complete pest control solution
May require supplemental feeding in gardens with low prey density

Attracting Mantises to Gardens

Plant diverse vegetation for hunting and perching
Avoid pesticides that kill mantises and their prey
Provide water sources (misting, water features)
Leave some areas undisturbed for ootheca attachment
Purchase and release oothecae from reputable suppliers

Mantises as Pets

Praying mantises have become increasingly popular as pets.

Advantages of Mantis Pets

Low maintenance compared to many pets
Fascinating to observe
Short lifespan allows observation of complete life cycle
Educational for children and adults
Relatively inexpensive to keep
No need for walks, litter boxes, or extensive space

Basic Care Requirements

Enclosure: Well-ventilated with height for molting
