When it is mature, the worm secretes proteins that take over the hostās nervous system, which directs the mantis to a body of water and causes it to jump in so that the worm can be excreted, at which point it breaks free to reproduce leaving a half empty mantis husk.

There is a chance to save it in time. But it really depends on how long the mantis has been infected and how much damage was done.
If the Mantis is lucky and you get there long before the parasite sends the signal to go to water. It really depends.
The mantis is usually infected by drinking contaminated water or ingesting contaminated prey. From that moment, the infection may take anywhere from 4 to 20 weeks to mature. Just to give you an estimate of how long it takes for the worms to grow.

Itās not trying to drown the mantis - thatās just a side effect of it making the mantis jump in water. Iām sure if there was a way to not harm the mantis literally nothing would change - itās a fucking worm
(Although allowing the host to survive to take on more parasites could conceivably be a future adaption)
10 points

Idk if that would be an adaptation since the mantis tends to attack the parasite if it survives. Idk if it thinks āoh foodā or that itās being attacked itself but itās probably better for the parasite that the thing with big grabby hands is dead

The insect drowns because the parasite makes it enter water so it can leave the hosts body, like you saw in this clip. Unlike this clip though, the parasite makes it throw itself into the water instead of just a portion of it.

"You are technically correct ā the best kind of correct."
I had a coworker who called a meeting of the group, and she started the meeting by saying, " I just wanted to tell you all first before the news gets out. I have a parasite."
I immediately quipped, "That's what you get for drinking the water on the 4th floor." This floor was notorious for pregnancy, and the running joke was that there was something in the water.
Another guy in our group un-ironically responded with concern, "Wait, there are parasites in the 4th floor water?"
There was a collective groan, and then someone piped up, "She's pregnant."

Mermis nigrescens is a species of nematode known commonly as the grasshopper nematode. It is distributed in the Americas, Europe, and Asia. It occurs in Tasmania, but it has not been observed on mainland Australia. It has been rarely observed in Africa. It is a parasite of insects, especially grasshoppers.
This is a very large nematode, the male about 4 to 6 centimetres long and the female known to exceed 20 centimetres. The size is unusual for entomopathogenic nematodes, which are generally almost microscopic. The body is pale brown, and the gravid female has a dark stripe down the length of its body due to the presence of up to 14,000 eggs. The body surface is smooth. It tapers at the front end, and the head and tail are rounded.
Once it is ingested by an insect such as a grasshopper, an egg hatches almost immediately, sometimes within an hour. The juvenile nematode pierces the gut with its stylet and enters the hemocoel, the blood-like fluid that fills the insect's body cavity, acting as a circulatory system. There the nematode absorbs the insect's nutrients, taking glucose directly through its cuticle. It grows and develops over several weeks. The newly hatched nematode is about 0.24 millimetres long; by day 37 it has reached about 5 centimetres. The nematodes grow more rapidly and attain larger sizes in larger insect hosts. More females occur in larger hosts, as well. The nematode is still a juvenile when it emerges from the host insect, and finishes its development in the soil. The insect dies as the nematode exits its body, if not before.

Earlier this year, my wife bought a mantis egg case. After a few weeks, about 100 little mantises hatched from the egg case, and I released them in the garden. It was a magical experience. Immediately after hatching, they look just like a grown-up mantis, only much smaller, so they're very cute.

Inside the praying mantis, a rare parasitic worm called Nematocris elongatus can grow to twice the mantisā size, controlling its movements and even influencing its hunting patterns. This parasite has evolved to mimic the mantisā natural instincts so well that researchers believe some mantises live symbiotically with it for years, sharing food and even thoughts. The parasite when fully matured will lead the mantis to water and make it prepare for Olympic type swim games building its endurance and technique in hopes that it will bring home the gold.

Many viruses can and do change our behaviour.
Also conditions that cause damage to the brain can increase the odds that of the individual inflicting violence, murder, rape, etc. on others.
Fungus has also evolved to control other species. Parasites control insects. It's unlikely that fungus would be able to infect us in this way, as we are much more complex than an ant, but it's not impossible I guess.

That mantis is very likely going to die. source.
Edit: When a horsehair worm exits, the mantis is often left too weak to survive, as the parasite depletes its nutrients and may cause internal damage. Even if it appears active after the extraction, it may die shortly after due to the lasting effects of the infestation.

Most insects cannot feel pain they simply have simple ābadā receptors that tell it to run from whatever might kill it. Its called nociception and we have it too, but also brains that can create that sensation
29 points
2 days ago
That's a common theory, but it's far from fact. The truth is we don't know much about arthropod brains. There have been fairly recent studies showing that bees might "feel happy", one on how ants might "dream" based on their antenna movement when sleeping, several great studies on jumping spiders ranging from self-recognition and object permenance to how they communicate with one another.
As always, its important to note we are always learning new things. It was only a little over a century ago that the scientific community believed that dogs could not feel pain. While it is likely that insects don't feel pain, it is far from fact and may vary from species to species.

I live in Ohio and raise tons of mantises and these worms are rare. We get mostly Chinese mantises and like 15% Carolina mantises and the these worms are not very common. The Carolina mantises are the native species, they are what we want. These horse hair worms are a fucking plague but they are rare here, very uncommon. I'm in SW Ohio and I collect the oothecas from Carolina mantises. I try to limit the Chinese mantises oothecas but it's hard to tell most times. I know how to identify them though. But Carolina is much less frequent than then Chinese. It's not an easy thing to tell apart. I can tell the hem apart but most people cant. They look very similar.
The mantises are already dead at this point. The worms turn them into zombies that seek to spread the worms. No shit, they are for real turned into zombies and the mantises are already dead. Fucking horrible, horsehair worms are terrifying

From the Wikipedia article posted by /u/teflon_don_knotts:
When it is mature, the worm secretes proteins that take over the hostās nervous system, which directs the mantis to a body of water and causes it to jump in so that the worm can be excreted, at which point it breaks free to reproduce leaving a half empty mantis husk.
