This super creepy parasite lives inside insects and forces them to drown themselves
A short video shows what's living inside many praying mantises, crickets and other insects.

Yikes!
At Upworthy, we love to share cuddly, feel-good videos of heartwarming stories about animals.
This is not one of those stories.
Behold, today we offer instead a video of a parasite crawling out of a praying mantis. Sure, it might not be as cute as a beaver building a dam out of household items, but rest assured, it’s mesmerizing in its own dark and twisted way.
Shared by @WowTerrifying on Twitter (with the original video being credited to “Insect World”), the video shows a mantis gently having its bottom submerged in water.
Only a few seconds go by before these super creepy, spindly, dark black lines start crawling out of the mantis, and they clearly have a mind of their own. Honestly, it’s beyond gross. The only silver lining here is that the person handling the mantis appears to be offering help to the poor creature.
Watch below…at your own risk.

This nightmarish sight is a parasite known as a horsehair worm, which is best known for a) looking a bit like the symbiote from “Spider-Man” and b) hijacking an insect’s nervous system to control their minds. Usually the latter entails getting insects like mantises and crickets to drown themselves in water so that the horsehair worm can lay eggs…thus repeating one of Mother Nature’s more morbid cycles.
If you’re feeling traumatized, you are not alone. Pretty much everyone who saw the video shared their instant regret.
“That’s enough scrolling for me,” one person lamented.
“This will haunt me,” wrote another.
Sure, the natural world is full of wonders both beautiful and terrifying, but it never fails to provide something fascinating.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
