Praying mantis green macro

The praying mantis is a predatory insect famous for its 'praying' posture and camouflage skills, playing a key role in biological pest control.

About this subject

The praying mantis, also known as mantis religiosa, belongs to the order Mantodea, comprising over 2,400 species worldwide, mainly in tropical and subtropical regions. Its name derives from the posture of its front legs, which resemble hands in prayer. This insect is a voracious predator, feeding on flies, crickets, grasshoppers, and even small vertebrates like lizards. Camouflage is its primary hunting strategy: the elongated body and green or brown coloration allow it to blend seamlessly into leaves and branches, remaining motionless until prey approaches.

A striking feature is sexual cannibalism: the female often devours the male after or during mating to obtain additional nutrients for egg production. The oothecae, frothy structures that protect the eggs, are typically attached to stems and trunks. Development is incomplete, with nymphs resembling wingless adults. The praying mantis has a triangular head and large compound eyes capable of rotating 180 degrees, providing exceptional binocular vision for calculating attack distances.

Culturally, the praying mantis symbolizes patience and focus in many societies, revered in Chinese folklore and African traditions. Despite its name, it is unrelated to religious practices; the designation is purely descriptive. In Brazil, it is common in gardens and rural areas, contributing to ecological balance by controlling herbivorous insect populations. The most well-known species is Mantis religiosa, introduced to North America and found worldwide.
