Identifying Signs of Parasitic Infection in Praying Mantises

Parasites can wreak havoc on the health and well-being of praying mantises, causing significant changes in their behavior and physical appearance. By being able to identify the signs of parasitic infection, you can take steps to help your mantis overcome this potentially harmful condition.

Abnormal Behavior

One of the key indicators of a praying mantis having a parasite is changes in its behavior. Some common abnormal behaviors to look out for include:

  • Increased Aggression: Parasites can often cause a mantis to become more aggressive than usual, attacking other mantises or even their caretakers.
  • Lethargy: A parasitized mantis may appear sluggish and uninterested in its surroundings, showing little to no energy or motivation.
  • Erratic Movement: Parasites can disrupt a mantis’s nervous system, leading to erratic movements such as twitching or spasms.

Physical Appearance Changes

In addition to changes in behavior, parasitic infections can also manifest through physical appearance alterations. Some signs to watch for include:

  • Abnormal Coloration: Parasites can affect a mantis’s ability to properly molt, resulting in abnormal coloration or patterns on its exoskeleton.
  • Swollen Abdomen: A mantis with a bloated or distended abdomen may be harboring parasites within its body.
  • Visible Parasites: In severe cases, you may be able to see the parasites themselves either inside or outside of the mantis’s body.

By being vigilant and observant of these signs, you can quickly identify a parasitic infection in your praying mantis and take appropriate action to address the issue. Remember to consult with a veterinarian or experienced insect enthusiast for guidance on treating parasitic infections in mantises.

Common Parasites Found in Praying Mantises


Nematodes are one of the most common parasites found in praying mantises. These small, worm-like organisms can infect the mantis by entering its body through various means, such as ingestion of contaminated food or water. Once inside the mantis, nematodes can cause a range of symptoms, including weakness, lethargy, and decreased appetite. In severe cases, nematode infestations can even be fatal to the mantis.

Parasitic Wasps

Parasitic wasps are another common parasite that can affect praying mantises. These wasps lay their eggs inside the mantis, and when the eggs hatch, the larvae feed on the mantis from the inside out. This can lead to severe damage to the mantis’s internal organs and eventually death. Parasitic wasps are known to be a major threat to praying mantis populations in the wild.

Overall, it is important for mantis keepers to be aware of common parasites that can affect their pets and take steps to prevent infestations. Regular monitoring, proper hygiene practices, and quarantine procedures can all help to protect praying mantises from parasites.

Steps to Take if You Suspect a Praying Mantis has a Parasite

Isolation and Observation

If you suspect that your praying mantis has a parasite, the first step is to isolate the infected mantis from any other insects you may have. This will help prevent the spread of the parasite to other insects in your collection.

Next, carefully observe the behavior and physical appearance of the mantis. Look for any unusual symptoms such as lethargy, discoloration, or abnormal movements. Parasites can often cause changes in the host’s behavior and appearance, so it’s important to take note of any abnormalities.

Seeking Professional Help

If you believe that your praying mantis is indeed infected with a parasite, it is crucial to seek professional help as soon as possible. Contact a veterinarian or an experienced insect specialist who can properly diagnose the parasite and recommend appropriate treatment options.

Do not attempt to treat the parasite on your own without proper knowledge and expertise, as this can potentially harm the mantis further. Professional help will ensure that the parasite is properly identified and treated, giving your praying mantis the best chance of recovery.


In conclusion, it is important for those who encounter praying mantises to be aware of the signs of parasites. By observing the behavior and physical appearance of these insects, one can potentially identify if they are infected. If a praying mantis is suspected to have a parasite, it is best to contact a wildlife expert or veterinarian for further guidance. This knowledge can help protect the praying mantis population and prevent the spread of harmful parasites.
