Excerpt
Ouch! Watch Where You’re Sticking That! from Chapter 12
When it comes to mating, the male bed bug may be the most indelicate of all insects. It is uncouth indeed, and perhaps lazy, or at
least guilty of taking the most drastic of sexual short cuts. There would seem to be no good excuse for its unsavory habits, insofar as both male and female possess the necessary sex organs and systems to allow for
a more conventional sex act.
The female, for example, possesses the typical reproductive organs and system of other respectable insects. She has a pair of
ovaries for producing eggs, the ductwork to deliver eggs to the outside, and a perfectly nice vagina
to accommodate a perfectly nice penis for mating. The male also has the requisite organs and system to accommodate the female; however, the manner in which he employs his penis is where he may be
labeled a sexual deviate.
Stabbed for Sex
Rather than inserting his penis into the vagina of his mate, as any respectable
male might do, the male bed bug bypasses the conventional route. He stabs the female’s body with his penis, poking through the body wall to ejaculate his
sperm into her body cavity or into other tissues and organs modified for receiving the sperm. Such an extraordinary act requires an extraordinary
penis. Some have described the bed bug penis as a “veritable Swiss army knife of gadgetry” to cut through the female’s tissues (Thornhill & Alcock
1983). It is modified like a dagger or knife to penetrate the female’s body. Some related bugs with similar sexual habits have a huge, bulky penis that is
designed to cut through the vagina and the body cavity to deposit sperm directly in the female’s sperm storage organ (Thornhill & Alcock 1983).
Females are not without their own special equipment and design. Some female bed bugs have a special Organ of Berlese to protect against damage due to “traumatic insemination” by males and have
no external opening to the vagina (Berenbaum 1995). Furthermore, they have devised a way to digest much of the semen that has found its way into the body. In some bed bugs, sperm actually
find their way to the heart, where they accumulate and eventually get distributed with blood to the sex organs or digested along the way (Chapman 1998).
If being stabbed for sex were not bad enough, the injury is followed by the
insult of scars on the female body. In some bed bugs, you can determine the number of matings by counting the healed penis wounds on the female’s body. Such a scar must be the insect equivalent of the Scarlet Letter.
