Hairworms, also known as Nematomorpha, are a group of parasitic worms found throughout the world. Two types of hair worms, Chordodes formosanus and Spinochordodes, are known to parasitize praying mantises. Although these worms share some similarities in their life cycle, they also have some notable differences.
Chordodes formosanus and Spinochordodes praying mantis hairworms infect their hosts in a similar manner. The eggs of these worms are ingested by the praying mantises, and the larvae emerge in the host’s intestine. The larvae feed on the food consumed by the praying mantis and grow inside it. Finally, the worms emerge from the praying mantis’ body, usually through the abdomen, and then seek a nearby body of water to complete their life cycle.
Despite these similarities, there are some notable differences between Chordodes formosanus and Spinochordodes praying mantis hairworms. One of the main differences is their preferred host. Chordodes formosanus infects a wide variety of insects, such as crickets, cockroaches and butterflies, while praying mantis hairworms generally parasitize praying mantises.

Another difference between these two types of worms is their geographic distribution. Chordodes formosanus is native to Asia, specifically China and Taiwan, while praying mantis hairworms are found throughout the world, including North America, Europe and Asia.
Both types of worms are known to manipulate the behavior of their hosts, which can be dangerous to the praying mantis. It has been observed that hairworm-infected praying mantises may be more likely to move closer to the water, increasing the chances that adult worms will reproduce and deposit their eggs in the water. In addition, it has been observed that Chordodes formosanus can cause its hosts, such as crickets, to feel a strong attraction to light, which can put them at risk of being hunted by other predators.
If a hairworm emerges from the body of a praying mantis, the praying mantis generally survives without problems. However, hairworm infection can affect the behavior of praying mantises. For example, it has been observed that hairworm-infected praying mantises may be more likely to move closer to the water, increasing the chances that adult worms will reproduce and deposit their eggs in the water.
What if these worms could infect humans?
Praying mantis hairworms are a type of parasitic worm that infects praying mantises, but what if these worms could infect humans? If these parasites could jump from their natural host to humans, they could have serious consequences for human health.
Imagine that someone accidentally ingests hairworm eggs in a body of water, such as a pool or lake, and the larvae emerge in his or her gut. The larvae feed on the internal organs of the human host, which could cause severe internal damage and lead to long-term health complications.
Furthermore, as in the case of praying mantises, hairworms in humans could manipulate the behavior of their hosts. This could lead to dangerous situations, such as infected humans feeling an uncontrollable urge to head for bodies of water, putting their safety at risk.
