About this subject

The praying mantis (order Mantodea) is a carnivorous insect inhabiting tropical and subtropical regions worldwide. In Brazil, it is common in Cerrado, Atlantic Forest, and even urban gardens. Its common name comes from the posture of its forelegs, resembling hands in prayer. In fact, this stance is a hunting strategy: the insect remains motionless for hours, waiting for prey to approach, then captures it with a rapid strike that takes less than a tenth of a second.

A striking feature of the mantis is its triangular head, which can rotate up to 180 degrees, providing binocular vision and depth perception. This ability is rare among insects and crucial for calculating the exact distance to prey. They feed mainly on flies, crickets, grasshoppers, and even small lizards or birds. Females are known for sexual cannibalism: after mating, many devour the male to obtain nutrients for egg production.

Praying mantises play an important ecological role as natural pest controllers and are used in some countries as biological control agents in agriculture. Their camouflage is remarkable: green and brown colors help them blend with leaves and twigs. Additionally, they display a deimatic behavior when threatened, raising their body and spreading wings to appear larger. The life cycle includes egg deposition in oothecae (foamy structures) that protect the eggs during winter or dry season.
