Parasitic Wasps invade a Caterpillar's body

Nature is horrific.

This species of Wasps inject caterpillars with larvae eggs, that hatch and devour the pray from inside. Later on they infect their hosts brain with a virus, making it into a kind of wasp bodyguard.

Kill it with fire..

Wow, if nature is this freaky (scientific term..) on Earth, I wouldnt fancy being the first person to go for a stroll on an alien world

Zonbiesays...

God was in a bad mood when he came up with this one...

Seriously though, I find parasites fascinating, as so far they can go to manipulate the host...

Bruti79says...

Also, isn't there something that happens to mice when they have a parasite, that makes them more aggressive towards cats?

grintersays...

Toxoplasmosis will make mice less cautious around cats, or even attracted to cat urine. There are also good examples of parasites affecting the behaviour of fishes, making them more susceptible to predation by birds, and of fungus affecting the behaviour of ants, causing them to climb up trees, where they can better disperse fungal spores.

Soooo....we invented a caterpillar internal camera?

Also this disproves the bible. god couldn't possibly love ALL his creations if he did this to one of them.

omnistegansays...

Oh god, I figured the wasps would eat it and kill it inside out, but no.... I thought they would paralyze it and kill it, but no.... It starves to death. All that and it starves to death? Wow, someone pissed off Buddha last time around.

Xaielaosays...

That's f'ing disgusting. But it's just one example of many natural systems that work like that.

And yes, we don't need any alien viruses to take over our minds when it happens all over in the natural world. Thankfully our brains are far to complex for these viruses to actually work on us. But who knows what could happen, with evolution and time.

GabaJsays...

this reminds me of an interesting fact:

"The number of bacteria living within the body of the average healthy adult human are estimated to outnumber human cells 10 to 1"
ScienceDaily (June 5, 2008)

there is more "them" living in you than there is "you" in you.
