For African bat bugs, the battle of the sexes is quite literally a violent struggle—and now it appears that the bugs are using gender-bending tactics to defend themselves.
Bat bugs are small, reddish-brown parasites related to bed bugs that suck the blood of bats and sometimes bite humans.
Researchers have long known that male bat bugs ignore females' conventional parts and instead use their sharp penises to stab the females' abdomens, injecting sperm directly into the bloodstream.
So the females evolved a defense: structures called paragenitals that guide a male's needle-like member into a spongy reservoir of immune cells.
But the females aren't the only ones in need of protection. Observers documented males performing the same injurious sexual acts on other males.
Now evolutionary biologist Klaus Reinhardt of the University of Sheffield in England has discovered that male bat bugs have developed their own versions of female paragenitals to avoid the assaults.

This could explain barking moonbat bugs in the democratic party. Or not.

This article serves as another grotesque reminder of the purpose of sex...
To impede reproduction.

Observers documented males performing the same injurious sexual acts on other males.Proving, of course, that homosexuality is perfectly normal and natural. If the bat bugs do it......

Yeah, well when National Geographic News reports that since the female Praying Mantis rips the head off the male after they “do the nasty”, the male has evolved, by growing a fake head, THEN THAT WILL BE HEADLINE NEWS!
