Female Praying Mantises Sometimes Eat Their Mates

In the world of praying mantises, the line between love and cannibalism can be blurred. Female mantises are known to occasionally consume their male partners after mating, a behavior referred to as sexual cannibalism. While it may seem shocking, this act serves a biological purpose, providing the female with essential nutrients for reproduction.

Research suggests that cannibalism among praying mantises occurs between 13% and 28% of the time among species that exhibit this behavior. When female Chinese mantises consume their mates, they can lay up to twice as many eggs as they would under normal circumstances, benefiting from the additional protein and nutrients obtained through this feeding strategy.

The phenomenon of mantises consuming their mates is not limited to insects. Startlingly, there have been 147 documented cases of praying mantises eating birds in 13 countries across six continents. In the American Northeast, the Chinese mantis has been responsible for 25 recorded incidents of consuming birds, with Ruby-throated hummingbirds being the most common victims. The European praying mantis, on the other hand, has exhibited a voracious diet, including prey such as frogs, lizards, shrews, mice, and even birds.

Resource Scarcity and Mating

A curious study involving praying mantises fitted with 3-D goggles discovered that these remarkable creatures possess 3D vision based on movement rather than the complex patterns perceived by humans. With approximately one million neurons, mantises efficiently see in 3D, despite having far fewer neurons than the human brain’s 100 billion.

One fascinating characteristic of mantises is their lack of pupils. Instead, they have a pseudopupil, an optical illusion created by the arrangement of light receptors in their compound eyes. This unique visual system enhances their hunting abilities.

The occurrence of sexual cannibalism in praying mantids, impacting male mortality during the breeding season, has drawn the attention of evolutionary biologists. It is believed that this behavior may have multiple unrelated causes, indicating varied underlying reasons for cannibalism. A 1994 laboratory experiment revealed that female mantids only cannibalized their mates when they were starved. This finding emphasized the link between resource scarcity and the female’s decision to consume her mate. Females that were well-fed did not display this behavior, regardless of male courtship intensity.

Praying Mantises Can Rotate Their Heads 180 Degrees

Praying mantises possess a fascinating and unique ability to rotate their heads nearly 180 degrees. This periscopic mobility allows them to have an extensive field of view, enabling them to spot potential prey, predators, or other threats with ease.

Therefore, efforts towards environmental preservation and conservation play a crucial role in maintaining the delicate balance of our natural world.

They Lay Their Eggs in a Protective Case

As part of their fascinating life cycle, adult female praying mantises lay eggs that are covered with a soft protective egg case called an ootheca. The ootheca, commonly referred to as a protective foam, serves as a shield for the developing eggs and provides them with a safe environment to grow.

The ootheca is made up of a foam-like substance secreted by the female mantis. It hardens over time, forming a durable casing that protects the eggs from predators and harsh environmental conditions. This ootheca acts as a natural shield, ensuring the survival and proper development of the embryos inside.

Depending on the species and environmental variables, it may take anywhere from three to six months for the nymphs to emerge from the ootheca. During this period, the ootheca regulates temperature and humidity, ensuring optimal conditions for egg development.

The Chinese mantis (Tenodera sinensis sinensis) ootheca is one of the most common types found in North America. It is so widely recognized that commercial biocontrol suppliers sell these egg cases for pest control purposes.

The Protective Journey from Ootheca to Nymphs

Once the eggs are laid inside the ootheca, they undergo a period of development before hatching. The egg case typically takes around 3 to 10 weeks to hatch, releasing tiny nymphs into the world. These nymphs are miniature versions of the adult mantis but lack wings and are not yet sexually mature.

During their developmental journey, praying mantises molt multiple times, shedding their exoskeleton as they grow. This process, known as molting, allows the mantises to accommodate their increasing size until they reach adulthood.

On average, praying mantises have a lifespan of around 6 to 12 months, although this can vary depending on climate conditions. Throughout their lives, mantises feed on a variety of creatures, including flies, spiders, small insects, nesting birds, tree frogs, and even small snakes. Their predatory nature makes them beneficial insects in farming, as they help control harmful insect populations.


The praying mantis is truly a fascinating insect with remarkable adaptations. Its ability to rotate its head up to 180 degrees showcases its incredible neck flexibility, allowing it to scan its surroundings without moving its body.
