Wasps use their penises as deadly weapon to sting predators who try to eat it

Wasps are said to use their penises as a deadly weapon to sting predators attempting to eat the horrid little insect strain.

Japanese scientists were stunned to discover that the razor sharp genitals delivered a killer sting to those attempting to harm, eat or kill the winged beasts.

Female wasps were shown to have a venomous sting, but male wasps were seen to have a spiky genital capable of dissuading the most horrifying of predators.

All it takes is a jab from an aedeagus, the insect version of a penis, to deliver a blow against an attacking predator, although boffins noted they do not use them against their mates.

Interested in figuring out the circumstances for a wasp to take a plunge against a predator, Japanese scientist Shinji Sugiura at Kobe University set about exploring what did and did not consist of a threat.

Scientist Shinji said: "The male wasp used a pair of sharp spines in the genitalia to pierce her finger.

"Surprisingly, the male ‘sting’ caused a pricking pain. I hypothesised that the male genitalia of A. gibbifrons function as an anti-predator defence."

Putting forth a poor frog for the test showcased that every male wasp in the container would attack the frog.

This does come before the frogs successfully eat the wasp within the container, but it does show that the wasps were able to frequently pierce the mouth and face of the test frogs.

Said sting was delivered with a genital shock, with the wasps using their aedeagus to attack the provoking tree frogs and pond frogs.

Shinji added: "Because wasps and bees evolved venomous stings from ovipositors [the tube used to lay eggs], their males, which lack ovipositors, were believed harmless. However, we found that male wasps use the genital spines to counterattack predators."

Female wasps were tested also, but appeared to test very badly, only stinging the tree frogs.
