A new study of C. maculatus seed beetles has proven the worst case scenario for most men: size and in this case the number of painful, injuring spikes on their penises do in fact matter. The C. maculatus have a series of spikes and barbs on their members that, during sex, become embedded in their mates, acting as anchors of sorts.

We are so sorry, but what you are looking at is EXACTLY what you think it is.

“They literally injure females internally in their copulatory duct. They’re pretty mean,” Goran Arnqvist, the lead author of the study, said to National Geographic.

After looking at a large group of diverse, virgin beetles after copulation the study concluded that the beetles with the “largest and most damaging” phalluses had the most reproductive success. The injury to the females was simply an “unfortunate side effect” of the process. Holding tongue. Not making joke. Holding tongue. Holding tongue….

More entomologically hardcore images below the fold…

Is that the Statue of Liberty? Nope, another beetle penis!

One species of seed beetle actually has a jaw like spine structure on its appendage.

    Five things come immediately to mind:

    1. Looks like Cimex lectularius has some competition…
    2. Why does the first picture remind me of Momaw Nadow?
    3. “Just relax, baby, it’ll only hurt for a little bit.”
    4. On whose fingertips is this travesty occurring?
    5. Everything’s bigger under electron microscopy

    America still treats it as the root disease. This new NSS seems little more than smoke and mirrors to me, substituting costly counterinsurgency for cheap counter-terrorism. Not only will counterproductivity result, isn’t this a tacit admission that al-Qaeda really is bleeding America out?
