Terrifying new wasp species discovered with a giant stinger

Scientists have discovered a new species of wasp that resembles something from an Alien movie. The parasitoid wasp called Clistopyga crassicaudata was discovered in the Amazon rainforest by researches from the University of Turku. The new wasp species has a terrifying stinger which is not only long but also very wide and it uses it for a very gruesome purpose!
The species was found amongst the insect specimens collected a transitional zone between the Andes and the Amazonian lowland rainforest. The newly discovered wasp is different from other known species of wasp because of its giant stinger.

The newly described parasitoid species belong to the rare Clistopyga genus that uses its large stinger to lay their eggs into spiders or spider egg-sacs. The wasps seek out spiders living in nests, then using its giant stinger the wasp will inject venom into its victims to paralyze them, next the wasp will pump its eggs inside the host spider and the hatching larva will then eat the paralyzed spider as well as possible spider eggs or hatchlings.

The researches who discovered this new wasp have also found many other new species of wasp in the same area which they have named in the latest issue of the Zootaxa journal.

    • They’re hideous, I once saw some youtube footage of some ‘Bottlings’ being extracted from a girl’s shoulder. Gross!!

    • My girlfriend reckons that the greatest day of her medical career so far was the day she had someone walk into A&E with botfly larvae growing in their back.

      Apparently it’s not actually that uncommon, even in Cramlington.

    • The coolest thing about some botfly species is that their host animals have evolved a flight response to hearing the characteristic buzz. Instead of attacking their hosts directly the female flies, therefore, catch other parasites such as ticks or other flies and load their undersides with sticky botfly eggs, which are then transferred the next time the intermediate vector visits their shared host!

      Parasitology has some of the finest examples of evolution in action!

  1. The “stinger” is called an ovipositor, if you look at Ichneumons in the UK they have the same equipment, but they don’t “sting” people because they can’t, it’s an egg laying tube.

    I think you’ll be quite safe from them.

    • Yes. Most years there will be a story in the tabloid press about someone ‘terrorized’ by a giant wasp that turns out to be an ichneumon fly or a similarly harmless woodwasp.

  2. Lots of grim things like that in the world, as well as insanely ingenious parasites. Like the wasp that affects the behavior of its ant host making it climb to the top of a blade of grass so it gets eaten by a cow which is then the second host for the wasp’s young. Parasite Rex is a great book about all this:

    • Almost…

      You were thinking of a liver fluke (Dicrocoelium lanceolatum) that infects first a snail and then an ant which will climb up a flower or grass stalk before fixing itself to the plant through a parasite induced mandible cramp…

      Other, related parasites infect a snail’s brain, and makes the eye stalks swell, develop coloured rings, and wave around like worms to attract birds.

      Certain unicellular parasites (Toxoplamsa sp.) that eventually infect cats play the same game with mice and rats, making them more curious and less afraid of open spaces, and even interested in cat urine, increasing the chance that the rodent gets eaten!

      The really scary thing is that there is good epidemiological evidence that this also affects humans (e.g. significantly higher toxoplasmosis rates in juvenile traffic accident victims compared to control cohorts, suggesting that brain infection may potentially promote reckless behavior).

      This is just another reason why letting a cat shit outside the owner’s house is criminally antisocial behavior.
