Mantis is the common name for insects in the order Mantodea, a group of predatory insects known for their triangular heads, bulging eyes, and enlarged, spined forelegs used to catch prey. The common name “praying mantis” comes from the upright posture many species hold while waiting to strike. Mantises are present in Canada, especially in warmer parts of the country, and are of interest to gardeners and naturalists as predatory insects that can help control other insect populations.

Taxonomy and naming

Mantis refers to members of the order Mantodea. In common usage, “praying mantis” is often used for these insects, though the term is sometimes applied broadly to the whole group. The largest family within Mantodea is Mantidae, and the order contains about 430 to 460 genera with over 2,400 species.

Physical characteristics

Mantises have triangular heads, prominent compound eyes, long neck-like prothoraxes, and enlarged front legs with spines for seizing prey. Many species are green or brown, helping them blend into vegetation. Their bodies are elongated and adapted for ambush predation.

Behaviour and diet

Mantises are ambush predators that wait motionless and strike rapidly at prey. They feed mainly on living insects, and some species also consume spiders, frogs, lizards, or small birds. Their spined forelegs grip prey securely once caught.

Distribution and habitat

Mantises occur in many parts of the world, including tropical and temperate habitats. They are especially diverse in warm regions. In Canada, they are found in warmer areas and are noted for their role in controlling insect populations.

Human interest

Mantises are often viewed as beneficial by gardeners and farmers because they eat insects that may be pests. They are also widely known for their distinctive posture and appearance, which has led to the common name “praying mantis.”

Key facts

  • Mantises are an insect order, not a single species.
  • They are distributed worldwide, especially in tropical regions, with some species in temperate areas.
  • Their front legs are adapted for grabbing prey with a spined, gripping mechanism.
  • Many species are called “praying mantises” because of their folded forelegs and upright resting posture.
  • Over 2,400 species belong to the order Mantodea, with Mantidae being the largest family.
